SUMS Reviews 

Really swift delivery and good product. I have experience some bobbling on first use of two of the pairs which is unexpected for expensive socks claiming to be for ultra use!

The Quarter Crew socks are brilliant—comfortable, durable, and perfect for any run. They stay put, feel great, and handle every distance effortlessly. Highly recommended.

Been a SUMs supporter from day 1 and have used them from local races to Badwater 135. Got a dreamy 300 miler lined up and SUMs are the first things going on the must wear list

First time ordering SUMS. Kept reading positive recommendations. Great ordering experience with order coming quickly. And so far after one run, really enjoying my new socks!

Had a few issues with the earn per run but they persisted with sorting the issues out and credit to them got it resolved. Always send their products out promptly and all the gear is great quality. Bought quite a lot now and love to.

Great company. I have ordered 2 pairs of running socks. They arrived very quickly. Those socks are super comfortable. Love the colors and the support they provide while running. At first they felt a bit tight but I think that’s how they should feel. After 6k run they stayed at the place without any rubbing or even feeling like my feet are sweaty. No blisters whatsoever. Love it. Perfect socks for runners. Thanks Sums!

Well made socks with good colours. I felt the fit is too tight for my liking - I am UK 11 and wonder if an XL size word work better.

Love SUMS , I bought a pair in a shop in london and couldn’t resist to order a few more.

I just started running literally 2 weeks ago and the socks from Sums were just the best! Zero blisters (even running 10km as a beginner with not much training). And honestly, the socks are so cute?! Like they’re muted enough to not shout for attention but also still makes a statement. I’ve recommended them to some of my friends. Need to order more.

Mint, comfy socks, love the colours and designs. More importantly though after last few runs in other socks I had blisters on toes and heels, first run in sums socks no blisters at all! Very happy 😃 👍🏻

The best running sock there is, can use them on any and all runs, tough socks that can withstand long days on trails and cause zero frictions no blisters on my marathon PR of 2:58! They look sick as well

Have 7 pairs of Sums now, I’m a UK12 so ordered Large, first three pairs I ordered were great but a very neat fit. I ordered four more pairs recently, same size, much better fit! Particularly enjoying the cushion deluxe. I will definitely be buying more for my running rotation. Great socks and a good discount on multiple pairs.

Great socks! Worn for my first Olympic distance triathlon. Feet felt great in the heat.

The ease of navigating the website, finding out exactly what I wanted and what was in stock, was super easy. The color selection and sock styles were exactly what i was looking for. Will definitely be buying from Sums again.

This is now my 7th pair of SUMS socks, I bought the first pair for my first ultra 3 years ago and now they are my only running socks I use! All 7 pairs are still in rotation, I constantly recommend them to people! They are the best socks on the market!!

Arrived quickly, great fit. Bought a number of times now. 😊

I’ve been wearing SUMS for a few years now and will not run in anything else. Comfort, quality and excellent customer service put them head and shoulders above anyone else. Once you’ve run in a pair of SUMS - the white all-seasons will quickly become your go-to - you won’t go back.

Get involved.

Fantastic product. Makes a huge difference to my running. I'm not normally one to buy into these things but I bit the bullet and got a pair. I would definitely recommend these and will be buying another pair soon.

Great socks, fairly pricey though. And the marketing strategy gets you, almost pressuring you to purchase the bundle deal for greater savings and free postage! Unfortunately, I pulled a muscle in my calf during my first run wearing the Sums ! Nothing to do with the socks; the socks are the most comfortable I’ve ever worn!

Efficient service and quality product. The socks feel great to run in and I’m enjoying the colour schemes. Thank you!
