November 19, 2025—Boulder, CO — Lems Shoes, the Boulder-based footwear brand known for its commitment to natural foot-shaped designs, is hitting the road — literally. In Fall 2026, the company will launch its first-ever road running collection: the RadMaker and RadUltralite. Both models will debut at The Running Event this December, marking Lems’ official entrance into performance running.

“Entering the road category has been years in the making,” said Andrew Rademacher, founder of Lems Shoes. “Our new road running collection is engineered to provide proper toe alignment, optimal metatarsal spread, and a streamlined fit. Designed with our fit-first approach, this new collection prioritizes performance, efficiency, and foot health in a category that is often dominated by fashion and cushioning trends.”

For this new collection, Lems developed its first-to-market TrueFit last to give runners a more natural, efficient ride. Built around the true shape of the foot, the last keeps the big toe properly aligned and allows all five toes to splay on impact, supporting better stability and power transfer. Its sleek profile removes the bulk and unwanted movement common in wide-toe box shoes, creating a more secure, responsive fit. The result is a smoother, more comfortable experience on the road.  This new collection is an evolution of Lems’ fit-first philosophy that has guided every design since day one.

Lems RadMaker: Built for the Long Run

The RadMaker is Lems’ first road running shoe, built on the healthy fit and low drop that define Lems footwear. Designed for the everyday runner, it’s engineered with the Natural Running Platform to promote a smooth midfoot strike and a stable, energized stride. With a slight rocker, a foot-shaped wide toe box, and the new TrueFit last, every element works together to support natural biomechanics, lasting comfort, and efficient movement on the road.

Rad UltraLite: Fit-First Minimalism

The RadUltralite builds on the foundation of the RadMaker, stripping the design down to the essentials. With a 2mm drop, minimal stack height, and Lems’ Natural Running Platform, it delivers a low, stable feel with just the right amount of cushioning for zero-drop enthusiasts seeking an even closer connection to the road. The TrueFit last keeps toes properly aligned for natural foot health and a streamlined fit. Lightweight, durable, and designed for movement, the RadUltralite allows feet to perform naturally, wherever runners go.
