The Xero Shoes Speed Force II is a lightweight minimalist running and speed-training shoe for people who prefer a close-to-ground feel rather than a thick, cushioned midsole. Its flexible 4.5 mm FeelTrue rubber sole, zero-drop heel and foot-shaped toe box are designed to allow natural foot movement. The updated breathable upper includes welded reinforcements, while adjustable instep and midfoot straps help secure the fit. Xero lists approximately 6.5 oz (184 g) per shoe in a men's US size 9, with actual weight varying by size.
It is best considered for experienced minimalist runners, short faster sessions, drills and gym training, rather than runners who require substantial cushioning or a structured stability platform. The thin sole transmits more surface feedback and may be uncomfortable on sharp gravel or for anyone accustomed to maximalist shoes. A gradual transition from higher-drop footwear is sensible. Check the manufacturer's size guide and allow sufficient toe room, especially if wearing the shoe for longer runs.
