About the Birkenstock Air Cushion Full-Length Insoles
Overview
The Birkenstock Air Cushion Full-Length Insoles offer heel-to-toe cushioning to help alleviate pressure and provide all-over cushioned comfort. Designed based on footprints in sand, the insoles feature thinner cushioning under the heel and forefoot and thicker cushioning under the arch and metatarsals. Perfect for replacing your existing shoe insole with an insole that will provide more cushioning, or for adding additional cushioning on top of a flat insole for extra volume & cushioning. For those seeking extra foot cushioning, the Air Cushion Insoles are an excellent choice.
Description
The tops of these insoles are lined in Birko-Tex fabric, which will reduce foot friction to prevent blisters in addition to helping wick away moisture to keep your feet cool and dry. The latex foam body provides "springy" cushioning for your feet, with extra cushioning under the arch and metatarsals to help better absorb pressure where the foot is raised. Raised toe grips also help the toes find better traction within your shoes, helping prevent unwanted foot movement.
Notes:
- The heel & toe cushioning measures approximately 1-2mm thick, while the arch/metatarsal cushioning measures approximately 10mm thick.
- Made in Germany.
