I'm 6ft 1in, weigh 205lbs and depending on the brand I usually wear a size 11-12. I bought these boots in a size 11 based on the size chart and as me put them on, I thought I bought a youth size. I don't have very wide feet, but these didn't even come close. walking around and it felt like my foot was going to snap out from under my feet. I don't know what's wrong with these boots but I'm switching to another brand because these boots don't fit.
