Imagine a house constructed of steel and stone, but with a padded interior made of memory-foam. That's what you get with the Burton SLX: superior comfort surrounded by a stable and supportive S4 outer shell — built from the same material found in bullet-proof vests. The liner flexes and forms ideally, and the outer shell won't budge any more than necessary. Burton did us a solid here. Just ask Mr. Haakonsen — it's no wonder these are his go-to sole-supporters.
