Sizes do run differentlyNot as warm as I had hoped, but I also have nephropathy in my feet so they tend to get chilled pretty fast. They are comfortable and the sizing is true to size.Love the fur like lining of this boot. They are very warm. Very light weight but sturdy. The sole is rather stiff, but maybe they will break in more over time.Wish they had better styles and patterns.If you want a warm boot, this is a good choice.Did not know what to expect when purchased. Played the snow all day wore a heavy thermal socks and I was good all day. Not too sweaty or anything. The next day I wore again with a thinner winter sock no problem and one night had to go to parking lot to get something out of the car with no sock in the middle of mini snow storm with no problem. Of course I played in the snow for about 30 - 40 mins no socks and I was fine didn’t feel a bit of cold. Shoes worked well for me.The sued/letter leather feel synthetic but soft shell looks great. The interior is very warm even though the material is a thin outer layer. The color I chose is beige cream color so I shouldn't wear them much so they should last for a while even as an inexpensive pair.Muy cómoda y perfecta para el frioOMG everything they said that is good is with these boots! Loved walking all over Steamboat Springs winter time, feet nice and cozy warm and comfy fit the whole week. ?Warmth
