From a Tuesday 5k to a 40k race day, and everything on a Hyrox floor in between. These are built for the sessions where cheap socks start to matter. A 60% nylon body gives them the structure to hold shape through repeated washes, with 5% elastane keeping the compression honest session after session, and cushioning placed where feet blister first. Targeted compression through the arch and ankle — support where it counts, without the tourniquet feel of a full compression sock. Cushioned heel and toe box — the two failure points once the distance stacks up. Ventilation panels across the top of the foot, so heat leaves before it becomes friction. Zero-slip arch band — stays put through sled pushes, transitions and the last 10k. No bunching at the heel. 20cm crew height with a 3cm ribbed cuff — sits clear of the shoe collar, covers the lower calf, and stays where you put it. Composition: 60% nylon, 20% polyester, 15% cotton, 5% elastane. Nylon-led for durability and shape retention, with a touch of cotton for softness next to the skin. Worn by runners, triathletes and Hyrox athletes on start lines across South Wales. Sizing One size, UK 4–13. The compression knit stretches across the full range — a standard fit at the smaller end, closer-fitting at the larger. Still a proper compression fit at a size 13. Most one-size socks stop at 11, and the ones that don't tend to give up the compression somewhere around a 12. These hold it to the top of the range — so if you've spent years sizing out of "one size fits all", start here. Garment measurements, laid flat and unstretched: foot length 18cm, sock height 20cm.
