Nordica’s Ace of Spades boot has matured into the Ace line, at the top of which sits the 100-mm last TJS Pro. Nordica’s first-ever pro model boot goes to TJ Schiller and features a three-piece shell and progressive flex. The boot is agile while making slight adjustments in stance but progressively gets stiffer for support when going big. A burly liner and strategically placed foam in the shell also keep you comfy.
