Best socks I’ve ever worn

I've never given the socks I run in much thought, bought a few pairs of SUMS because they look sick then omfg, they are so comfortable. I've worn normal socks since, that I had run in before and I can feel such a difference. SUMS fit snug and comfortably close to the foot so they don't slip around at all on me.

Honestly… Sums socks blew my mind this weekend at Tribal Clash in Dartmouth 🙌 I had two pairs – one for Saturday, one for Sunday – and they handled everything. Saturday they went straight in the sea for the first workout, then I continued to wear the same pair for the worm, then onto the bars, running, climbing, you name it. Feet were soaked, sandy, sweaty… but ZERO blisters. Not even a hot spot. Sunday I took them on the 5k trail run (again, wet and muddy) and still came out with happy feet. No soreness. No rubbing. Nothing. Just solid comfort all weekend long. Genuinely didn’t think socks could make such a difference, but these did. Can’t recommend them enough – 100% worth it if you want your feet to survive a weekend like that 👌🧦

The best compression running socks! I had MONSTER blisters from doing a few 10KM+ long runs after wearing ordinary cotton socks, and needed to stay on top of my training, so bought these SUMS socks to see if they’d help - SO glad I did! They’re genuinely the only socks I wear on my runs now. Can’t recommend enough, and they look cool with any leggings or shorts as well. LOVE!

Absolutely great product, there are so many sick companies in the running space and Sums is quite easily one of the best in the game 💪💪
