Heel Fit System
The Heel Fit System (HFS) consists of anatomically sculpted pieces of foam padding which hold the heel comfortably and securely in place to avoid unwanted movement.




Trekking boots require a snug fit around the heel area to prevent unwanted movement which can lead to excessive friction and blisters. HFS is a system of anatomically shaped high quality foam padding which helps to comfortably hold the heel securely whilst accommodating different heel shapes.
