these shoes are fantastic! never thought slippers would fit like these do! and they stay on very well. very versatile: great for bouldering and all types of sport climbing.
i wear size 39 in testarossas, and these i can fit into 38 new, but i'd go half a size up unless the cramped toes are an absolute necessity, or if you need those heels to stay in every possible scenario. for comparison, i wear size 41 evolv talons.
