i would highly NOT recomend them.
they are very comfortable, but after about 2 sets, the top laces snap. i replaced them a good 10 times no exageration. then the material on the inside of the boot began to peel away. luckily my local shop is awesome. and he took them back and let me get a pair of hyperlite audios instead.
my buddy rides the byerly boa though, and the lace system is a little different on the tops, and he hasnt broke a lace. the metal rings they laces on the pros run through, just shreds them.
it wasnt just mine either. my dad had the same boots, and his laces broke all the time to. it sucks spending 400$ on boots, only to have to keep spair laces in the boat.
hope this helps!
