The third generation of Meindl’s innovative lacing system, Variofix 3 ensures a perfect, snug fit in the heel without uncomfortable pinching or undue pressure. The integrated heel harness runs around the heel and secures to the footbed.As you tighten the laces, the free-running “speed wire” strap is pulled in closely and evenly around the heel. This creates the most secure, comfortable hold for your heel, guaranteeing better, no-slip support.
