Does anyone know if the Teva Mush II or Teva Mush Original are zero drop? Or do they have a secrect wedge in the heel? I would like to order a pair but cannot tell from online pictures if there is any heel lift. The mush footbed looks like it would mold to the foot's sole plus offer protection from nasty objects and be slip resistant. Also any other current Teva models that are zero drop? The Teva's Zilch and Northridge not suitable due to toe straps not in the right place and the Nilch looks too enclosed. Looking for Tevas because I owned a pair of Teva adjustable multi strap sandals for years. Enjoyed their sole's protection and durability. Had to toss them due to the heel lift and tight toe piece becoming unbearable due to the barefoot/zero drop lifestyle.
