I'm 5'9" 195 pounds wear a size 10 shoe and i bought Regular 10. The fit is great, the waders almost come all the way up to my armpits and still allow for good movement and mobility. Keeping the insulation higher and allowing me to wade into deeper water is a huge plus. I mainly hunt very muddy areas and the waders do not get weighed down by the extra mud. I have been out about 20 times in them and during my last hunt i noticed a leak. I babied these waders and ensured i followed the script for proper cleaning/caring to a T. They do send a repair kit that I am hoping will remedy the job. But at this price i was hoping they would last more than one season. The 1600 gram insulation boot seems to only cover up to your ankle, not then entirety of the boot. Granted the temps have been in the low 30s in my area, i was hoping to have found a solution for freezing feet. In general i stay warm and can get away with less bulk/layers up top due to the nylon insulation. Overall they've been great except for the recent leak. That's the only reason i cannot give them 5/5 stars.
