ACCELERATE TONGUE

Add response when you want it.

The ACCELERATE TONGUE is a FLUX-specific insert that lets you adjust boot flex by sliding it into the pocket on the boot tongue.

Its highly reactive material is designed to increase response through carving and speed up turn transitions when you want a more aggressive feel from the boot.

Includes two ACCELERATE TONGUE inserts.
