STRICTLY LIMITED ONE-TIME RELEASE
An exclusive Riot Labs release, created in response to community demand. A super smooth & comfortable quarter-length technical running sock. We spent over a year developing the perfect running sock, dialling in the fit, compression and cushioning until every run felt better.
This exact sock will never be produced again: once it's gone, it's gone.
FlexForm Fit (UK 4-10)
A flexible, adaptive unisex fit designed for most, with our optimal comfort range at UK 4–10. Targeted arch support for stability, strategic cushioning for impact absorption, compression zones for support and recovery, and a breathable nylon/elastane blend for moisture management.
Community note: If you're outside the FlexForm size range of this limited drop, please get in touch. Your feedback will help us understand demand for extended sizing in any future variant releases.

Running is more than chasing your personal best. It’s release. It’s focus. It’s time free from interruption. It’s time for thought. Or no thinking at all.
We’re on a mission to make running tops that you love for their comfort, performance and look. Chafing seams, poorly placed labels, overly clingy or heavy materials… say goodbye to anything that stops you from focussing on your run.
Everything we make is for the everyday runner who appreciates both practicality and considered design. Our flagship product is The Essential. We set out to create a premium running T-shirt that matches the skin-soft feeling of cotton, with the performance and resilience of technical fibres.
Every item we produce starts with a sketch. The details matter. Form. Fit. Function. Not a stitch out of place.
Run. Release. Feel better.
It’s simple but profound to us. Running lifts your mind as much as your body, and that’s worth shouting about.
If you’re struggling, running can help. But CALM helps even more. That’s why we’re donating £2 from every Essential Tee sold to support their life-saving work.
