The 650s are comfortable boots. I just put them on and went to work and had no hot spots or problems at the end of the day. My only complaint is the sizing which is why I'm giving these boots 4 stars. I'm a size 9 in Bates and my Asic running shoes are a 9 but I had to exchange the Bellevilles for a 8. Just keep in mind they run large. Great boots otherwise.
