The original FASTLIFT is back! Delivering stability, support and structure in the heel and mid-foot, this remains an outstanding option for weightlifting. Unlike some other lifters, the FASTLIFT 335 boasts excellent flexibility and comfort, meaning it can be used for all aspects of workouts and WODs, not just for weightlifting. We have graded the fit of all our shoes from 1 to 5 to make it easy for you to find the perfect fitting shoe. All our shoes are designed with Met-Cradle technology to lock down the mid-foot for a stable hold. Where they differ is in the toe box. Grade 1 represents our closest, most precise fit. At the other end of the scale, Grade 5 has the widest fitting toe box. We have meticulously studied the foot and its function during the gait cycle and also the interaction between the foot and the terrain. We have used this knowledge to develop our fitting scale. For technical footwear a good fit is essential to enhance your performance. As a rough guide, Grade 1 represents an industry B fit, while Grade 5 equates to a 2E fit in the forefoot.Shoes details:Outsole rubber holds secure on the box/gym floor, especially when lifting heavy weightsExternal Heel Cage and POWER-TRUSS technology gives lateral stability and a stable base for liftingVelcro strap over the top of shoe adds a second layer of mid-foot hold after laces have been tiedMETA-FLEX technology in the forefoot provides more comfortable movementsAllow transition from Olympic weightlifting to other functional movements in the same workout
