Prudhoe Expert
I walk about 4000miles per year & have found PHD 's to be the best all round sock ive used to date.They keep their shape & are very odour resistant , having a good balance of elasticity & marino wool.Last over 500 miles compared to a pair of Berghaus socks which wore a hole in them after 20
Paying £20+ for a pair of socks
