With such problems as swollen feet and lower legs it, helps to feel comfort and this therefore aids mobility and these socks give you that. Helpful to know that there may be a larger size available should my medical foot/leg problem worsted. It's good to see more patterned and colours available. At the moment washing in machine hasn't been a problem, but it is early days for my new batch of socks I have just purchased ( re previous problem as I informed you at the time and you acknowledge of hole under heel area in the socks with spotty pattern occurred after a couple of washes). I am quite confident in purchasing more from you as have had good wear of your plain socks.
