I wear a 11 street shoe and 11.5 in evolv climbing shoes ( I have 2 pair of evolv's) but I had to go with a 12 for the geshido lace up. Once I got the sizing worked out the shoe is great, five stars all the way. Good for everything from trad to sport to the gym. Just remember to size up a bit and you'll love 'em. And they are made in the USA!
