R.A.D® Unisex UFO Running Shoes - Acid Green

The R.A.D® Unisex UFO Running Shoes – Acid Green are road-running super trainers engineered to build speed across distance. Designed for runners who want responsive energy return without sacrificing the cushioning needed for higher mileage, the UFO combines dual-layer SUPEFOAM™, performance-focused rocker geometry, and a sculpted heel bevel to create a smooth, energetic ride for long runs, progression sessions, and threshold workouts.

The bold Acid Green colorway gives the futuristic UFO silhouette an unmistakable high-energy look. Bright, attention-grabbing styling complements the shoe's speed-focused design, making it a standout option for runners who want their training shoes to look as fast as they feel.

At the core of the UFO is R.A.D®'s innovative SUPEFOAM™ midsole, a dual-layer PEBA blend designed around a catch-and-release concept. The softer foam layer provides cushioning intended to improve running economy and reduce fatigue, while the firmer layer delivers powerful energy return as you move through each stride.

This dual-layer construction gives the UFO the versatility needed for a wide range of performance-focused training. The softer cushioning helps keep longer efforts comfortable, while the firmer, responsive layer comes alive when you increase the pace during progression runs and threshold sessions.

A flowing rocker geometry works alongside a carefully sculpted heel bevel to promote smooth transitions from landing through toe-off. The geometry is designed to keep forward momentum flowing, creating a dynamic sensation that encourages quick, efficient transitions as the miles add up.

With a substantial 42 mm heel stack and an 8 mm heel-to-toe drop, the UFO provides generous underfoot cushioning while maintaining the geometry needed for efficient forward movement. At approximately 249 grams for a men's US 9, it balances high-stack protection with the lightweight responsiveness expected from a modern super trainer.

The textile and synthetic upper provides performance-focused coverage and comfort, while a durable rubber outsole supplies the traction needed for consistent road training.

Designed specifically for road running rather than trails, the UFO excels when workouts call for sustained speed over pavement. Whether you're building endurance on a long run, gradually increasing the pace during a progression session, or locking into threshold effort, the R.A.D® UFO – Acid Green delivers the cushioning, responsiveness, and smooth transitions needed to keep you moving.
