Warm, Comfy and super Lightweight!
I normally wear a size 6-61/2 so I bought the smalls- they are a tiny bit big but not enough to worry about. These suckers are super light weight, comfortable, warm and fully water resistant. I took them with me to Mammoth for 5 days to test em out and they were fantastic. I just wore them with ankle socks and they worked in the bars and in deep snow. They kept my feet warm and dry (actually, extremely hot inside the bars)
My only gripe is that the DC logo is sparkly which I couldn't tell from the picture. I'm not a super girly-girl so I would have definitely preferred them without the sparkles. I'll rub em off if I can.
Overall- Love them and happy.
