Birko-Sport Arch Support by Birkenstock Blue Closed-cell Foam/Cork
The Birko Contact is a two-part insole system to support and cushion the foot during athletic activities. The deep heel cup keeps your feet in the proper alignment and keeps the foot's padding under the heel bone for cushioning on impact. The cork support stabilizes the metatarsal and longitudinal arches. The foam is washable and retains memory of your foot.
Best worn with sport shoes, ski boots and work shoes. Recommended for low to average arch feet.
