And next, be able to get half size different shoes !! That won't happen
I believe a lot of climbers 'need' this, I among them!
My left foot is longer but lower volume than my right so I am always taking off or loosening my left shoe first. Shoes that do not stretch at least 1/2 size just don't work for me.
100% agree. My left foot is a bit wider and at least 1/4 - 1/2" longer than my right. Evolv allows you to order two sizes.
Actually, the tolerance control on shoes sucks: There is generally quite a bit of variation within a given size. I know I use 9s usually, so I'll have the store guy bring me 4 or 5 pairs of 9s of the model I'm interested in, try on all the left shoes until I find the best one, then ditto for all the right. I'm sure I'm a pain in the ass, but I do buy the shoes from them. Because of this, it's kind of dumb to buy shoes online anyway.
