Light and powerful!
Probably the best ankle strap on the market. When adjusted properly you should experience no pressure points around that zone unless it is your boot! The toe strap is a pain to center if you have larger boots with a wide toe box. High back tech is killer with all the flex up top but plenty stiff in the heal cup for great response. No need to rotate!
I got the L/XL for my size 11.5 boots. If you run into toe strap issues, try adjusting the accelerator (if you have it set forward).
