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!

These were my first SUMs socks... already my new favourite. they really do fit your feet, so however wet and muddy you get there is no rubbing. Thanks

Brought 2 pairs to try them out. I got the all cushion deluxe and the all seasons. I took the all cushion deluxe on a modest 20km trail run and they are without a doubt the comfiest socks I’ve used so far. They’re that good, I decided to buy another 3 pairs the following week. Would recommend to anyone who’s in the market for a new pair and has had trouble with blisters in the past.

Bought these socks as had been recommended by a friend - love the design but most importantly they got me around my first marathon (untrained) with no drama at all. Thank you Will and Team Sums!

Brilliant socks, so comfortable and actually keep your feet comfortable on trail runs, really nice slight compression. Worn them for 3 muddy trail runs so far and they still come out clean and fresh.

Best socks I’ve tried (and I’ve tried a lot!). Used mine for trail and road running up to ultra distance and had no blisters at all.

Have a few pairs of both the All weathers and Ascenders and they've been great training through end of summer and now into the winter months. Appreciate the initiatives for recycling your old socks and the earn per run fundraising approach as well.
