These are the best socks I’ve ever had for trail running, every other brand I’ve used have meant that I’ve had to use various different methods to prevent blisters but the Tom Evans sucks from Sums have been so comfortable and blister free over long distances and challenging terrain. They are incredibly comfortable, even when wet and seem to dry really quickly rather that retain water when I’ve run through significant rain.

Wore my new socks on a 5 mile trail run this weekend. Wet and muddy but the socks were fantastic and super comfy.

Ordered a size 11UK and comes up so small it’s happened a few times which is disappointing

Really like the style of the socks but the sizing is inconsistant. I bought 3 pairs, one pair no probs to get on, the other two are so narrow they are a real struggle to actual get on and makes me not want to wear them.

You know when you’re excited that a pair of socks are clean and ready to wear again? That’s how I feel about my SUMS socks. Best socks in the drawer.

The best socks period. I've been wearing Sums for a while now and they are hands down the best socks for running in. Can't recommend highly enough, I've bought around eight pairs and use in rotation. The merino ones are perfect for this time of year as well!
