Originally bought for putting on my feet between sends when out winter bouldering but haven't had a chance to use them for that yet. Instead they are pretty damn good for wearing around the house, also worked well at the refugio in el chorro. The soles seem quite hard wearing, with occasional outside use barely noticable. Well worth the 24 quid I paid.
Got mine for the North Face store in London:
