ACE The ACE is a medium stiff, all-around, lightweight low cut shoe equally competent climbing micro-edges, thin cracks and steep friction slabs. The ACE has probably been used to put up more hard crack climbs in Yosemite and Joshua Tree than any other shoe. It is a favorite of trad climbers for its versatility and comfort - on routes ranging from one pitch crag climbs to do-it-in-a-day Grade V's and VI's. Board lasted for super support with semi-flexed shape and fully lined for dependable fit and predictable performance. Foam padded tongue (comfy), leatherboard footbed (molds to your foot print), lined back stay (more comfort) and 5mm of sticky FS Quattro rubber up front. FREE T-SHIRT with purchase! Fitting tip: if you wear a men's 10.5 US street shoe (UK9.5) order this size for comforatable crack climbing and long routes. I you want the ACE to be "stiffer" for standing on knobs and thin face holds go down 1/2 size to a UK9.
