Sadly Bridgedale seem to have replaced a long-standing (no pun intended) favourite of mine whose design has stayed pretty much the same for 15 years or so. Still, that's progress for you and whilst the old short coolmax sock they did would have easily got a 5 star review from me, this one gets 4 stars - they're probably the best short sock on the market now but knowing how good they could have been, based on the old socks, I find it hard to give them anything more.
FYI they're slightly cooler/thinner than the ankle length version of the Active Light Hiker Sock (or whatever it was called) making that perfect fit with my favourite Lowa Renegade Low Boots just a tad less comfortable.
