These have been great for long distance runs - saw me through 2 days of Ultra X Slovenia in the heat and no issues

Recently discovered these and tried them out, they give feel just right in giving a little support / compression, but breathable unlike others I’ve tried. These have now replaced all my other running socks, love them!

Love my lilac Sums -- they give my feet a fabulous pop of colour! Supportive but not tight. Very comfy -- I wear them for running and general gym training but actually need to ration myself because I could wear them every day!

Really good socks The perfect level of compression and cute patterns. I wish there were more colours and patterns to choose from. Price is high for socks but they do support your feet well.

The best running socks I have ever used. I got the purple checkerboard pair for myself and they soft and supportive without feeling like pressure bandages which I’ve found with other socks. No blisters with them, perfect for long or short runs. I’ll definitely be buying more!

Have 4 pairs now and use them for every run. I have had no issues whatsoever and so only have high praise for these socks.

Waited to use them on my long run today, I’m very impressed, great fit, without a doubt the best trail running socks I have used so far, no need to look anywhere else now. 10 out of 10 from me.

Just bought my second pair, and twi more pairs as presents for running friends. Can't reccommend Sums enough. My good luck charm for two marathons now, and all of my training. Worth every penny. Womens UK7 wears Sums M. Never had a blister since.
