Birkenstock Birko Sport Arch Support Insoles

Overview The Birkenstock Birko Sport Insoles are a two-piece insole designed to provide firm arch support, moderate cushioning, and replicate the feel of a Birkenstock shoe inside your own shoes. Featuring a foam top-cushion with built-in metatarsal padding plus a cork base that provides rigid arch support, the Birkenstock Birko Sport is a unique approach to foot support that is loved by many. If you're looking for the classic Birkenstock footwear feel, or if you're seeking firm support with metatarsal cushioning, the Birko Sport is an excellent choice! Description Looking at the insole, we'll first notice the blue foam top layer, which is completely separate from the cork base on which it sits. This foam layer provides a moderate amount of dense cushioning for your foot in additional to metatarsal cushioning via a built-in metatarsal pad. The toe area of the blue foam cushion also features toe grips similar to those found in Birkenstock shoes. The cork base provides rigid arch support
