I have been wearing evolv forever and thought I would try something a little different. After ordering an aggressive size for my foot I realized the Prism was extremely small. Tried 2 more times and finally found the right fit, which happened to be my actual street shoe size. After breaking them and getting used to the stiffness/angled toe I have grown to love them. The stiff toe is great for edging and providing nice power. The "magic fingers" heel feels secure and doesn't slip. I like how it conforms to the shape of the hold when used properly. The ONYXX rubber is super sticky and provides an extra level of confidence on flags. The uppers are amazing! The perforations keep my feet cool and comfy, which makes my feet sweat less and inevitably... don't make my feet stink! My evolvs would get nasty after a few sends. All in all, a great shoe. I primarily boulder but I can see them doing well in just about every aspect.
