We’re inundated with sport shoes that break, cause blisters, and you can’t clean without ruining. At Spartan, we build the hardest races and obstacles, and run thousands of miles testing them. The RD Pro was forged to be the best mud run and OCR shoe, with indestructible features for racing fast and training hard, in weather from perfect to hurricane.
Try breaking these, we dare you. The 5mm drop RD Pro has an ARC-foam™ midsole that provides a fast and responsive, race-tuned ride. Hydrain™ evacuates water fast, while a one-piece upper made from KPU (found on safety shoes) and technical mesh provides insane-level durability, while staying flexible. The OBSTA-tech™ outside rounds out a best grip shoe, including up and down while climbing.
