What Makes an Insole Sustainable and Non-Toxic

Most conventional insoles are synthetic foam with vague "eco-friendly" marketing behind them; Fulton's are made from natural cork, organic cotton, and vegan cactus leather, with carbon-negative production measured at -0.81 kg CO2e.

What Synthetic Materials Alone Can't Offer

Synthetic foam and gel insoles compress within weeks and are usually landfill-bound once replaced, with no specific material data behind most "eco-friendly" claims.

How Fulton's Natural Materials Support Both Body and Planet

The same cork footbed that molds to the wearer's arch after roughly 10 hours of wear is handcrafted in small batches in Porto, Portugal, from materials that skip synthetic foam stacks entirely.

Frequently Asked Questions

Are Fulton insoles non-toxic?

Fulton insoles are made from natural materials — a cork footbed, organic cotton, and vegan cactus leather — rather than the synthetic foams and gels used in most conventional insoles.

What materials are Fulton insoles made from?

The cork footbed forms the base of all three Fulton insoles. The Athletic Insole uses an organic cotton top layer, while the Classic and Universal Insoles use vegan cactus leather.

Are Fulton insoles vegan?

Yes — Fulton uses vegan cactus leather rather than animal leather on the Classic and Universal Insoles, alongside cork and organic cotton across the line.

How is Fulton's production carbon negative?

Fulton's manufacturing process is measured at -0.81 kg CO2e per pair, meaning the production process removes more carbon from the atmosphere than it emits, based on Fulton's published figures.

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.
