Shopped...read reviews, re-read everything again. Others shared oversize fit. I ordered my normal size...had it to do over, would again because I can wear regular OR thicker socks. Completely waterproof...have been in mud and deap snow. Breaks-in easily. I was worried about the back rubbing either my heel or leg. I have had no deal-breaker issues. I did get a tinder heel believed to be my fault with bad sock choice more than the boot. Initially, should take care to not wear a sock with slick-y type cloth. I have worn thicker & longer socks & now that the boot is "broke-in" they are my first choice. Bottom tread pattern cleans-up nicely. Design is sharp for a boot of this use-purpose. LOVE the slip-on design. LOVE the quality and should last me with care ...for a long time to come.
