If you are on the fence about buying these boots, just do it! Mine arrived a couple of days ago, and the fit is perfect! My main worry was that I am a 7.5 US. The instructions said to size down, so I did, even though I usually size up and use an insole. I got the 7, and they are just perfect. The material is so soft and stretchy that they mold to your feet. I’m so happy it rained today so I get to wear them!
They also have little drawstrings at the top that keep them from gapping at the sides. This is a problem I have with all boots that go up to the knee, but not these! If the sun comes out today, I’m going to try them in the folded down position. I’m going to be walking a lot today, and I already know these will be comfortable all day, rain or shine.
