I bought an Amber in 11.5, had a warranty issue (outsole was positioned oddly at the heel on the left shoe) and was promptly reimbursed, so I bought a Black in size 11 based on what I learned wearing the Amber 11.5. 1) sizing is probably narrower than the average shoe, good news for skinny feet and the material should break in around your foot shape. 2) length leaves plenty of toe room, so you may wish to size down if you do lots of walking up and down things you might catch a toe on. 3) slightly more than half of us have one foot bigger, and 80% of these have bigger left feet. Good news: both sizes/styles I tried had noticeably more room on the left than any other shoe I have tried. 4) not a stiff sole, and not much cushion. I'd recommend some sort of sports or anti-fatigue insoles if you are spending much time on your feet, and I wouldn't be wearing these on an enduro ride. These are more for being adaptable to the bike messenger life while looking great under the rolled-up cuffs of your Chrome fancypants.
