Birkenstock BirkoSport Arch Support Insoles

 The Birkenstock BirkoSport Arch Support Insoles are a  semi-rigid, two-piece, full-length insert that provides a deep heel cup  for natural cushioning and shock absorption, a natural contoured arch  support for longitudinal medial arch support, and a metatarsal support  cushion with a gently raised platform for raising toes into the natural  position. They are ideal for a low to neutral foot arch, BirkoSport are  constructed of Birkenstock's patently unique blend of natural cork lined  BirkoCork bottom piece insert with moleskin and a BirkoZell foam  cushion top piece. When combined, these things provide superior  cushioning and arch support for the entire foot length, however, both  pieces can be worn separately.
