The 1D10/1D11 Dynamic Foot improves on the SACH foot (solid ankle cushion heel) with a more a comfortable heel strike and easier rollover. The design uses the proven combination of a contoured core and functional foam. The unique foam technology improves the forefoot dynamic. In addition, the Dynamic Foot has a more natural shape. With its smooth surface and split toe cosmesis it is more inconspicuous for daily use. We developed the 1D11 especially for narrower womens and men's shoes, and it offers a slimmer foot shape than the 1D10. We recommend the Dynamic Foot for amputees who will walk both indoors and outdoors with some limitations.
