Thin Insoles

What separates "thin" insoles from other insoles?

Most shoe insoles have a thickness — measured at the forefoot of the insole (where the insole is flat) from the bottom of the insole to the very top of the cushioning layer — that is usually between 3-5mm. Insoles with this thickness generally can fit into most types of footwear without issue while also still providing good overall cushioning and pressure relief.

Thin insoles are insoles with a thickness that is 3mm or less. These insoles will usually fit well in even the most low-profile and tightest-fitting footwear, but will often have minimal cushioning throughout in order to save on thickness.

Thin insoles are a great way to add heel-to-toe foot support inside of tight-fitting, low-profile, or minimalist footwear such as dress shoes and cleats (as long as your existing insoles are removable) where other, thicker insoles would make the shoes too tight to wear.

Does this mean that thin insoles will be uncomfortable?

"Thin" does not necessarily mean "uncomfortable." Thin insoles will still provide your feet with a proper foundation, especially if you wear thin arch support insoles. This means that your feet will provide natural pressure relief and shock absorption for your body. The difference is simply how much pressure relief and shock absorption your feet will feel, with thinner insoles providing less overall cushioning and impact absorption compared to a thicker insole. However, we always recommend prioritizing fit over cushioning, and in low-profile footwear a thin insole is generally required for a good overall fit.
