UNISEX ALTURA CLIMBING SHOES The Butora Altura is a mid top trad climbing machine. The Altura excels at long days of multi-pitch crack climbing and big walls, but performs just as well on sharp micro edges. The 100% organic hemp lined German leather stretches very little, so the size you buy is the size you end up with. At Butora we take the details seriously, like how we use three different deniers of thread and don't use liquid adhesives on the upper, allowing better breathability. Whether in Yosemite, Indian Creek, or just at your local crag, the Altura's performance and comfort are so good you won't want to take them off. Sizing Advice: Altura comes in two colors (each a different width) the wide version of the Altura is Green. The narrow version of the Altura is Orange. Size up 1 size over street shoe for comfort, 1/2 size up for an aggressive fit (results may vary).
