These are my 5th pair of shoes. I've tried on every I could in the last year to try and get the perfect fit. There is not a Five ten in the universe that fits my feet both comfortably and tightly . This one does both for sure. I wear a 9 1/2 street and sized these down to 7 1/2. No stretch after 5 sessions the past two weeks. If you have narrow feet, a long middle toe and your heels slop out of the most cranked down Five Tens, give these a shot. The only thing is that I will resole w/ onyx after the vibram wears out.
