The 5.10 GAMBIT all types of climbing - indoor, bouldering, sport and trad. Fashioned from breathable micro-perf synthetic uppers. Lightly padded tongue, lycra taped opening and "5 finger" heel rand that applies firm. A neat new feature is the GAMBITS soft-eye and sub-surface lacing system - low profile and less to snag in-or-out of a crack. Outfitted with the latest 5.5mm Stealth Onyx Rubber - firmer, stickier and more durable than the rest. Used very little.
