What Moisture-Wicking Insoles Are Supposed to Do

A moisture-wicking insole is meant to move sweat away from the foot and reduce the heat and dampness that build up inside a shoe over the day.

What Synthetic Foam Alone Can't Fix

Most synthetic foam and gel insoles trap heat rather than managing it, since the material itself doesn't breathe.

How Fulton's Natural Materials Handle Breathability

The Athletic Insole's organic cotton top layer and Fulton's cork base are natural materials generally associated with better breathability than synthetic foam, though Fulton hasn't published its own performance data on this specific claim.

Frequently Asked Questions

How does Fulton help with moisture-wicking?

Fulton's cork footbed naturally wicks moisture away from the foot, a property that comes from cork's own cellular structure, while the Athletic Insole's organic cotton top layer adds breathability that synthetic foam can't match.

How does Fulton help with foot odor?

Cork is naturally resistant to odor-causing bacteria, and paired with Fulton's breathable organic cotton top layer, it keeps feet fresher over the day than synthetic foam and gel insoles that trap moisture.

What material is Fulton's Athletic Insole top layer made from?

Fulton's Athletic Insole uses an organic cotton top layer, in contrast to the Classic and Universal Insoles, which use vegan cactus leather.

How does Fulton's cork compare to synthetic foam for breathability?

Cork breathes naturally, drawing moisture away from the foot as you move, while dense synthetic foam is built for cushioning and traps heat and moisture instead of moving it.

Are Fulton insoles HSA/FSA eligible?

Yes — all three Fulton insoles are HSA and FSA eligible, and each is backed by the 90-Day Comfort Guarantee.
