The shoe features a full-length Goodyear rubber outsole and reinforced overlays, which reviewers note provide excellent grip and improved longevity. User and expert feedback report minimal wear after significant mileage, though some mention the upper mesh may show signs of wear over time.
The Skechers GOrun Razor Excess is widely regarded as a versatile, lightweight trainer with a firm, responsive Hyper Burst midsole and a 30mm/26mm stack height, making it highly suitable for tempo runs and uptempo efforts. Its low weight (7.1–7.5 oz) and rockered geometry promote quick turnover, which experts and users consistently praise for threshold and speedwork sessions. The cushioning is sufficient for long runs and marathon training, though some users find it a bit firm for very easy or recovery paces, and the ride is less plush than dedicated recovery shoes. Daily training is a strong use case due to its comfort, durability, and stability features, but the firmer ride may not suit all runners for every easy day. Racing suitability is high for 5K to half marathon, and even marathon for those who prefer a firmer, non-plated ride, but it lacks the propulsive feel of super shoes. Trail running is not recommended due to limited traction and a road-focused outsole.
Ideal for Best suited for intermediate to advanced runners who value a lightweight, responsive shoe for a mix of tempo runs, intervals, and longer efforts. Ideal for those with neutral gait seeking a versatile trainer that can handle both speedwork and daily mileage, and who prefer a moderately cushioned, rockered ride.
The Razor Excess is designed as a lightweight, highly cushioned, rockered performance trainer. The fit is secure throughout, with a snug midfoot and slightly narrow toebox. The shoe is plateless (no carbon plate in v1), but offers a stiff, responsive ride due to the high stack and rocker. The Arch Fit insole provides extra arch support, which may be noticeable for those sensitive to arch pressure. Best suited for runners seeking a fast, cushioned, and stable neutral trainer with a performance fit.
Sizing: Generally true to size for most runners; some with wider feet may find the fit slightly snug, especially in the forefoot. No consistent recommendation to size up or down, but those preferring a roomier fit may consider half size up.
