Heel cushions, heel pads, heel cups, heel wedges, and heel lifts can all look like tiny versions of the same product, which is why shoppers mix them up so often. Each one is actually built to solve a different problem, though, and choosing the wrong one can leave your heel just as sore as it was before. This guide breaks down what each type does, which kinds of heel discomfort each one suits best, and how to tell when a small heel insert is enough and when you need a full insole.

Heel Cushions, Heel Pads, Heel Cups, Heel Wedges, and Heel Lifts: What's the Difference?
Unlike full-length insoles, which replace the liner in your shoe from heel to toe, heel inserts are small pieces that address only the back of your foot. That makes them affordable, easier to move from shoe to shoe, and a popular first step for heel pain and soreness. The confusing part is the vocabulary, because brands use "heel cushion," "heel pad," "heel cup," "heel wedge," and "heel lift" loosely, and a single product can sometimes do more than one job. The descriptions below reflect how each term is generally used, and you can browse all of these styles together in our heel cushions and heel pads collection.
Heel Cushions and Heel Pads
Heel cushions and heel pads are relatively flat, cushioned inserts whose main job is to add padding and shock absorption under the heel. They make the most sense when your heel soreness is impact-driven, such as from long shifts on hard floors, running, or a heel that feels bruised. That bruised feeling can be literal, since Cleveland Clinic notes that stepping on a hard object can bruise the fat padding under your heel and leave it tender when you walk. Every stride begins with heel strike, the moment your heel first meets the ground, so cushioning at that spot takes on the first jolt of each step. Material matters here, too: gel is more shock absorbent and is the usual pick for high-impact activities like running and jumping, while foam is a bit better at passively absorbing weight and pressure, which suits everyday wear and standing. Because they're flat, cushions and pads are also the easiest type to slip underneath an existing insole.
Heel Cups
A heel cup adds a contoured back and sides to the cushioning, so it cradles your heel rather than simply padding it. That cradling keeps the heel centered and steady inside the shoe while still absorbing shock. Centering also protects the natural fat pad under your heel, which spreads outward under load unless something holds it in place, a principle we explore in our guide to what a deep heel cup actually does. Heel cups are a popular choice for general heel soreness and for anyone who wants a more secure, supported feel at the back of the foot. Because their raised walls take up more room than a flat cushion, it's worth making sure your shoe still fits comfortably once a heel cup is in place.
Heel Wedges
A heel wedge is an angled insert, often cushioned, that tilts the heel slightly inward or outward. The goal is to keep the ankle from rolling too far in either direction, which is why wedges are usually discussed alongside overpronation and supination. They're a fairly gentle tool, and someone whose foot rolls a lot will typically get more from a full arch support insole that guides the entire foot rather than just the heel. If you tend to roll inward, our overpronation insoles are a good place to start, and if you roll outward, take a look at our supination insoles.
Heel Lifts
A heel lift is an insert whose main job is to raise the heel, which makes it the one heel insert designed to change how high your heel sits rather than just how it feels. Some are single pieces of foam or cork, while adjustable designs are built from layers you can peel away or stack to fine-tune the height. People generally reach for them for two reasons, and the first is strain on the Achilles tendon, which we'll cover below. The second is a small difference in leg length: the American Academy of Orthopaedic Surgeons notes that more than half of people have a subtle leg length difference that usually causes no problems, and that a minor difference can be evened out with a small lift in one shoe. Larger differences, particularly those over about 2 centimeters, are more likely to affect comfort and are worth having evaluated by a healthcare provider. Our heel lifts collection includes both adjustable and fixed-height options, and our guide to adjustable heel lifts for leg length discrepancy goes deeper on that use.
Matching the Right Heel Insert to Your Heel Pain
Pain Under the Heel
Pain on the bottom of the heel, especially sharp pain with your first steps in the morning, most often points to plantar fasciitis, which Cleveland Clinic describes as the most common cause of heel pain. A heel cushion or heel cup can make that soreness easier to tolerate by softening the impact under the heel. Plantar fasciitis, however, involves the band of tissue that supports your arch, so a small heel insert alone often addresses only part of the problem. A full insole with firm arch support, a deep heel cup, and heel cushioning covers the whole area at once, which is the foundation of our plantar fasciitis insoles. If your discomfort is centered mainly at the heel itself, our heel pain and heel spurs insoles are another strong starting point. Many people begin with an inexpensive heel cushion and move up to an arch-supporting insole later if they want more complete relief.
Pain at the Back of the Heel
Pain at the back of the heel is a different situation. Achilles tendinitis, an overuse injury of the tendon that connects your calf to your heel bone, is one of the top causes, and Cleveland Clinic lists heel lifts among the ways to protect the tendon while it heals. A lift raises the heel slightly, which reduces how far your ankle has to bend, and how much strain the Achilles tendon takes, with each step. If a bony bump like Haglund's deformity is rubbing against a stiff shoe heel, a soft heel pad or lift can also change where the shoe presses. Our Achilles tendinitis insoles collection brings together heel lifts and heel-cushioned insoles for this kind of pain. Because the back of the heel can also be the site of more serious tendon problems, severe or lingering pain is worth having checked out.
Important: The Insole Store doesn't provide medical advice, and heel pain has many possible causes. If your heel pain is severe, gets worse, or doesn't improve after a few weeks, check in with a healthcare provider. Heel inserts can be a helpful part of a care plan, but they aren't a substitute for a proper diagnosis.
What the Research Says About Heel Lifts
Heel lifts have some promising research behind them, particularly for pain where the Achilles tendon meets the heel bone. In a 2024 study in the Orthopaedic Journal of Sports Medicine, 20 adults with this kind of Achilles pain wore 20-millimeter heel lifts inside their regular shoes. Their pain during walking dropped immediately after the lifts were fitted, and their symptom scores were better after two weeks of wear. The lifts were worn in both shoes so that walking stayed symmetrical, and no serious adverse events were reported. It was a small study with no control group that followed people for only two weeks, so the results are encouraging rather than conclusive. The lifts in the study were also fairly tall, at roughly three-quarters of an inch, and it's generally wiser to start with a modest lift and add height gradually, since too much lift too quickly can create its own discomfort. Heel lifts also work best as one part of a larger plan that includes rest, stretching, and supportive footwear.
Key Takeaway: Heel lifts are a well-established option for Achilles-related heel pain, with promising short-term research to support them. Cushions, cups, and wedges are comfort and alignment tools that can make everyday walking easier, but none of them is a cure on its own. Pairing the right insert with rest, stretching, and supportive shoes is a sensible way to approach lasting relief.
Using Heel Inserts With Your Insoles (or Instead of Them)
Over or Under: Where Heel Inserts Go
Where a heel insert goes depends on its shape and on the insole already in your shoe. Flat inserts, such as heel cushions, heel pads, and heel wedges, generally sit underneath your shoe insole, which keeps the feel consistent from heel to toe and keeps them from interfering with a contoured heel. Heel cups and other contoured inserts typically go on top of the insole, unless your insole already has its own contoured heel, in which case a flat insert is the better choice. Either way, seat the insert firmly against the back of the shoe so it lines up with your heel, and follow any placement instructions that come with the product. Most heel inserts don't have adhesive, since your body weight holds them in place as you walk. They're also usually sized by shoe size range rather than trimmed to fit, so check the size chart before you buy, and if your shoe feels tighter or your heel slips after adding one, try a thinner option or a roomier shoe.
When a Full Insole Makes More Sense
Heel inserts do one job well, but they only cover the heel. If your discomfort spreads into the arch, your feet tire out by mid-afternoon, or a heel cushion helps but doesn't fully solve the problem, a full insole is often the better move. Many full-length and 3/4-length insoles already include heel cushioning and a built-in deep heel cup alongside arch support, so you get several of these features in a single insert. Full-length insoles replace your shoe's liner and are the usual recommendation for everyday footwear, while 3/4-length insoles sit on top of your existing insole and suit tighter shoes, a choice we break down in our guide to full-length versus 3/4-length insoles. The two aren't either-or, either: some people add a heel lift or cushion to a shoe that already has an arch-supporting insole. If you're leaning toward a shorter format, our 3/4-length insoles are worth a look.
How to Choose the Right Heel Insert
Start with where the problem is and what it feels like. If your heel is simply sore or bruised-feeling from impact, begin with a heel cushion or pad, choosing gel for high-impact activity and foam for everyday standing. If you want a snug, cradled feel and more stability, a heel cup is the better match. If your heel or ankle rolls noticeably in or out, consider a heel wedge, or an arch support insole for more complete control. If the pain is at the back of the heel or you have a small leg length difference, a heel lift is the most relevant option. Whichever you choose, give it a few weeks to settle in before making a final call, and remember that all of these are over-the-counter options rather than a substitute for professional care. If you're still not sure where to start, our Insole Guide walks through choosing the right insole, and our Insole Recommendation Quiz can point you toward a match in just a few minutes.
Key Takeaways
- Heel cushions and pads are flat inserts that add shock absorption under the heel, heel cups cradle the heel, wedges tilt it, and lifts raise it.
- Cushions and pads suit impact-driven heel soreness, with gel favored for high-impact activity and foam for everyday wear and standing.
- Heel cups add stability and help keep the heel's natural fat pad centered, but they take up more room in the shoe than a flat cushion.
- Heel wedges are a gentle alignment tool for feet that roll in or out, while a full arch support insole typically provides more complete control.
- Heel lifts are the go-to for pain at the back of the heel and for small leg length differences. Early research on Achilles-related heel pain is promising, but it comes from a small, short study.
- Flat inserts generally go under your insole, while heel cups and other contoured inserts go on top unless your insole already has its own heel cup.
- Plantar fasciitis pain, or discomfort that spreads beyond the heel, usually calls for a full insole with arch support and a deep heel cup rather than a heel insert alone.
- Severe heel pain, or pain that doesn't improve after a few weeks, is worth having checked by a healthcare provider.
