I've been getting more into hiking this past year and started noticing my feet kind of roll inward, especially on longer hikes or when the trail gets uneven. I'm wearing Merrell Moab 3s. Is there an insole that could help with that?
What you're describing is overpronation, which is when the foot rolls inward more than it should with each step. On flat, even ground this might not bother you much, but on uneven trail terrain where your foot is constantly adjusting to rocks, roots, and shifting surfaces, it becomes more noticeable and can lead to arch soreness, heel fatigue, or ankle discomfort over time.
The Moab 3 is a solid boot, but like most hiking boots, its stock insole doesn't offer a lot in the way of dedicated arch and midfoot support. Swapping it out for a purpose-built hiking insole can make a real difference. Here are our two top picks:
CURREX HikePro Insoles
The CURREX HikePro is designed specifically for hiking boots and does a great job addressing exactly what you're dealing with. It features a firm arch support that works dynamically with your foot, supporting it without restricting its natural movement. That matters a lot on trail terrain where your foot needs to respond to what's underfoot. The deep heel cup is designed to flex independently from the rest of the insole, which helps lock the heel in place and cuts down on that inward rolling motion through the midfoot and arch. A memory foam layer provides solid cushioning without adding unnecessary bulk, and bamboo charcoal material helps keep things fresh on longer outings. One important note: the HikePro is available in Low, Medium, and High arch height options, so make sure to choose the one that matches your arch type for the best fit and support.

Superfeet Hike Cushion Insoles
The Superfeet Hike Cushion is another excellent hiking-specific option, and worth considering if you'd like a bit more cushioning in the mix. Superfeet's stabilizer cap cradles and controls rearfoot motion, which is key for keeping the foot from rolling inward on uneven ground. The midfoot support is solid without being overly stiff, giving your arch the lift it needs while still allowing the foot to move naturally through each step. The added cushioning layer makes this a great choice for longer hikes where foot fatigue tends to set in toward the end of the day. Unlike the HikePro, the Superfeet Hike Cushion uses a single arch profile, so there's no need to choose between sizing variants. It's a simpler setup, though it may not be as precisely tailored to very high or very low arches.

Summary
Choose the CURREX HikePro Insoles if you want a more tailored fit for your arch type and prefer a support-focused insole with dynamic heel control; it's the stronger pick for addressing overpronation directly. Choose the Superfeet Hike Cushion Insoles if you'd prefer a simpler setup with a bit more cushioning underfoot, making it a great option for longer hikes where overall foot comfort is the priority alongside support.
