I bought these to go on a trip to Washington DC. Since I live in Florida we mostly wear flip flops or sneakers.. So, I needed something to get through the time we were there since we knew it was going to rain and snow. They kept my feet dry and warm. Not to mention I walked over 23,000 the first day in them and did not have sore feet, no blisters, nothing. All and in all it was a great buy for this trip. As far as the longevity is concerned I wouldnt know because I only wore them for a short time and might wear them again for the one week its cold in Florida..
