it's not cold here in Wisconsin jet but the boots feel pretty comfortableThese are really good boots, they don't hurt my feet, which most boots do. The only reason I didnt give 5 star, is because my feet are cold even at 40° walking in water and snow at work. I wear these 13 hours a day and they are holding up very good so far.I have large calves and these did not fit due to that. Other than that, it fits to size.Very nice durable material. Fit like gloves, comfortable for my hard work in the wineries. Look forward to wearing these boots in winter.I will use to do my work.First off, I have 11 4E feet, and have always had a hard time with boots. I ordered the Muck Arctic Ice Mid, now that I, through incomprehensible circumstances, find myself up near Cleveland...from NC. I couldn’t even get my foot into the Chinese 11 Muck. I then found the completely amazing Bekina Thermolite in 12. These are incredibly well built industrial safety boots with plenty of wiggle room. They stand up...you put your foot into the boot and walk away. These aren’t for short trips to Whole Foods, but for those times when you need serious protection from cold, wet, mud and damage. Reinforced toe box, Kevlar foot bed, superior cold rating. And about $30 more than comparatively insubstantial Mucks...which seem more suited to perusing the cows at the 4H barn than anything serious.
