I felt I won the lottery by scoring these boots as I kept checking for weeks Atomic Moto WS for size 46 availability (non-Gore-Tex) and usually got Out-of-Stock for my size. Well I lucked out and order landed. As usual, fast shipping and good communication from AM. SG-22 fit me great right out of box. Felt way more flexible / walkable vs. new SG-12 that I ended up selling as being too stiff less communicative wrt foot controls. I like the Enduro's more aggressive sole, more traction when dragging a stuck bike out of the weeds /mud. I currently wear Gaerne Fastback Enduro, 46. Not waterproof, thus I went with the SG-22 Enduro Gore-Tex. Seems a bit stiffer but they're new and I expect they'll loosen up. Sg-22 toe box is bigger, wider and taller, IMO. I like the room for heavy socks and being able to move toes around. I have not trail ridden them yet..this weekend I expect a couple hundred miles on them. Hopefully I can come back and edit review. Boots from AM always a good purchase experience.
