The EX MP is exclusive and sold in stores and doctors offices only and not available for online purchase.  Please check the Retail Locations page for a store near you.  If you have any questions about availability, please contact us. The Cadence EX MP is the same as the EX with the addition of a metatarsal pad for additional support under the transverse arch of the foot to better distribute pressures under the forefoot.  The EX MP provides contoured semi-rigid support with exceptional shock absorbing comfort in the heel and forefoot. The EX MP includes an upgraded smooth lower friction CoolMax® top cover and a stiffer shell when compared to the Original Orange and Low Volume models.
