The Quantum is an aggressive looking shoe designed for all day sending. The comfy-ness of this shoe cannot be overstated. We wore it pitch after pitch despite the aggro downturned toe… or maybe because of the downturn! Compared to stiff, all day classics like the TC Pro or the Scarpa Vapor V, the Quantum is soft, supple, and sensitive, and the downturn allows your feet to reel you into the wall on steep terrain. Sensitivity comes with a price, and our testers paid for it with burning calves on long, less than vertical slab and knob pitches in Tuolumne Meadows.
Not to be confused with old Five Ten Quantum (a more aggressive purple colored lace-up similar to the Five Ten Arrowhead), these shoes were designed with input from the mighty Huber Brothers. Alex and Thomas are masters of El Cap granite, steep limestone, and even free climbing in the sub zero conditions of Antarctica. Our testers were curious to see what they would put into a shoe, and it seems like comfort and sensitivity are high priorities for the brothers.
