Five Ten's stiffest shoe with a supportive midsole and sole designed for cracks, slabs and all-day routes. Think big doses of performance and comfort for long routes. Five Ten's patented S-lacing and padded tongue gives a comfortable glove like fit. A stiff mid-sole provides edging power and all day support when you're a half dozen pitches off the deck and only half way to the summit. Lined Perfalon uppers are highly breathable and stretch resistant, with sticky Stealth ONYXX outsoles for durability and high-friction dependability.
