I purchased this pair in Charcoal and they were so true to colour. Very durable. I wore them to camping and long-distance walk. They don't slip the rubber is really good. The only reason why i gave it a rating of 4 is, when i first got them i struggled putting them on because i got big calfs. It took me too long fitting my feet in for the first few times, but later on, the material got lose and now i can easily put them on any time.
