Ultra Lightweight Performance Breathable and Durable Design Secure and Adjustable Fit If you’re looking for the closest thing to a true barefoot experience, look no further than the Speed Force II – a stylish upgrade to our original Speed Force. Steven Sashen, our CEO, Co-Founder, and Masters All-American sprinter designed the Speed Force with a former Nike developer. It’s the shoe he trains and races in. Since we released the original Speed Force, people have worn this ultra lightweight shoe for working out, pickleball, taking a stroll and everything in between.
