Designed by our CEO, Co-founder, and USATF Masters National Champion, Steven Sashen, with a former Nike developer, this is the shoe he wears for training and racing. Since we introduced the original Speed Force, people have been using this ultra-lightweight shoe for cross-training, pickleball, walking, and a variety of other activities. More Breathable, More Stylish The Speed Force II is our lightest performance shoe, weighing in at just 6.5 ounces each (Men's Size 9). Remove the optional insole for an even stronger barefoot feel and an even lighter shoe! The biggest change: A new, sleek, and ultra-breathable upper with welded overlays for added durability. Secure Barefoot Feel The signature adjustable instep and midfoot straps aren't just stylish, they're functional, letting you feel confident and secure in the Speed Force II for any activity. The 4.5mm flexible FeelTrue® rubber sole gives your brain the feedback it needs to help you move more effectively, efficiently, and enjoyably. A dual-chevron tread pattern grips the ground securely, and like all Xero Shoes, the Speed Force II comes with our 5,000-mile sole warranty.
