Description

Adjusts how deep the heel cup is molded — shallow cups allow easier fit in low-volume dress shoes, while deeper cups increase rearfoot motion control, proprioception, and cushioning. 14mm is our standard, 8mm is shallow, 18mm is deep and 22mm is very deep. We are happy to exceed even a 22mm heel cup but that instruction must be specified on the prescription form. Deep heel cups are frequently recommended for plantar fasciitis and posterior tibial tendon dysfunction.
