GREEN GUM $160

Select Size Size Guide

This shoe fits true to size. Size up 0.5 if you usually do in runners.

The R.A.D® R-1, our debut running shoe, forms the base of our running line. The tuned midsole technology, SwellFoam N2™, provides cushion for long runs and enough pop for tempo & interval sessions. The R-1 will be the workhorse of your running shoe rotation. 

  • - Tuned for Running
  • - Bubble Tech Energy Return
  • - SwellFoam N2™ midsole

      SwellFoam N2™ is our supercritical foam midsole technology, ideal for running footwear. It’s partly made from sugar cane, which captures carbon from the atmosphere as it grows and reduces our reliance on traditional, fossil-based materials in production.

      Swell Foam N2™ uses a 50/50 cane/fossil composition, a 20% bio increase from the Swell Foam in our training shoe. The supercritical foaming process allows us to utilize a higher bio content whilst still maintaining the performance attributes needed for running.

            We’re a small, young brand working hard to make the best product responsibly. We’re reassessing our business practices in every stage, from sourcing and production to shipping, packaging, and beyond.



            We use the same philosophy we would when training. We make marginal gains, step-by-step improvements, and keep progressing as we pass each milestone.



            That’s what we mean when we say we’re Tuned For The Future.

            SwellFoam N2™ is our supercritical foam midsole technology, ideal for running footwear. It’s partly made from sugar cane, which means it captures carbon from the atmosphere as it grows and reduces our reliance on traditional, fossil-based materials in production.

            We are striving to make a wave of change, and we aren't there yet: but every wave starts with a swell.
