Upgraded with a more rigid frame and stable base, the flexible Nike Free Metcon 3 cross trainers are even better for lifting and side-to-side action. Breathable mesh uppers with abrasion-resistant rubber support up the sides. Lace-up adjustability with Flywire cables for a locked-down fit. Bootie construction with a pull-tab at the back for a sock-like feel. Midfoot cage and rigid sides lock feet in place while allowing for unrestricted movement while lifting and training. Cushioned insole. Softer foam midsole with a firm carrier for better stability for heavy weightlifting. High rubber sidewalls resists abrasion during rope climbs. Rubber outsole with deep grooves for flex and expansion. Imported. Weight of footwear is based on a single item, not a pair.
