Every pair of socks I have seem to peel down my heels as I walk and end up bunched around the bridge of my foot for the day. Doesn't matter whether they are ankle, footie, sporty, have rubber grippy thing or not. I am about to throw out every sock I own (and given how many I've tried over the years, it's a lot) so I need a way to keep my toesies cosy. Can anyone recommend some please?
