LD Mountain Centre Says:
These liner socks from Bridgedale are made from Coolmax a wicking fibre designed to move moisture away from skin to keep you cool and dry. Ideal to use as a liner sock with one of the other Bridgedale walking socks. Or as the name suggests these great socks will work equally well on their own in your everyday shoes.
Bridgedale Coolmax Liner Sock Features:
Fine-knit, soft Coolmax® provides moisture wicking performance for dry feet. Aids hygiene and cleanliness. Recommended to be worn under other Bridgedale socks.
Previous Large Smartwool liner socks were too big for my size 9's with the sock heel riding up the back of my ankle. So bought a pair of these in a medium and whilst they are still too big (!) they're a better fit. I suspect a Small would be too tight, so this for the moment is the best option. First wearing on a 4 mile walk and no blisters or bits rubbing.
