Crank or cruise, VELCRO or LACE - it's totally your choice with the JOKER. Fit comfortable and wear all day or size down for precise sport climbing performance, bouldering or indoor moves. What's exciting about the JOKER is what you can't see - the EVA internal shock absorbing heel pad - which adds considerable comfort to impromptu landings, mandatory walk offs and even hanging out while belaying. This model fits comfortably wide, yet due to the leather and nylon speed lacing fingers, or Velcro - can be laced snug - even for slender feet. JOKERS are lined with Air Net mesh, fitted with a padded breathable tongue and equipped with an all leather footbed. Underfoot is a half length medium-soft midsole for balanced support and sensitivity. FS Quattro Rubber is a big story with this shoe - from the dimpled heel cup to the hand applied rand extending up and over the big toe. Soles are size graded super firm and super sticky FS Quattro rubber that has molded in Boreal and FS-Quattro logos - you've got to try it to believe it! Size 1 down from running shoe size - ie if you wear a UK 10 (US 9) street shoe order a UK 8.5 (US 9.5) for a close yet comfortable fit.
