I got a pair of these last season for base camp and around the house and they did not disappoint. Super packable (very small pack down), incredibly comfortable and surprisingly durable. The outsole is very tough and will really take a beating. I use mine mostly in the snow, but have used them on the barren cold ground and they tend to deal with debris just fine. I wear a 10.5 in most shoes and I bought the XL which fit great with a hiking or winter sock.
