These black sandals are new in box, size 7. The soles are rubber and the inner and outter material is suede. These have a 1.3in cat heel non slip rubber. All my items come from a smoke free home. Any questions please feel free to contact me. These sandals have a supportive latex insole that precisely conforms to your arch and heel, distributing pressure evenly and preventing soreness even after prolonged walking or standing.
