These boots have the best fit, stiffest but most comfortable lateral flex, but still let you tweak it side to side. The Imprint 4 liner is so comfortable and warm, you forget you are even in a stiff boot. I have ridden them on pow days, hard pack, steeps and jumps and they excelled in all these conditions. The speedzone laces do wear out, have had to replace a few, but over all, these are the best boots I have ever owned. Sold on these for life!
