Salomon boots are glorified rental boots.
they use cheep materials and over price their products. They put stupid gimmicky things on their boots to try to fix problems that arise when they really should just make a better boot. I made the mistake of buying the KAOS and get the worst toebang of anything I've ever ridden in.
Idk if Full Tilts are the messiah of boots but SPK's definitely are not. they look cool but thats about it.
