These shoes climb very well considering how comfortable they are. They do have a very narrow toe box. If you want to climb with these buy you typical street shoe size. If you want them to be a little more comfy for walking around, go up 1/2 size. I prevented the problem mentioned by a few others of the rubber peeling off before it happened by reinforcing all the seams with McNett Seam Grip. I apply seam grip to any shoe that I know will be taking some abuse.
