Lane Eight sneakers in light gray. Stylish and comfortable. Pre-loved Wore once In great condition Lunar Grey Meet the world’s best workout shoe: the Trainer AD 1. It’s designed for everything from base runs, box jumps, and burpees, and it’s made with sustainable and recycled materials like algae and plastic. The Trainer AD 1 is designed to have a snug fit, but will break in and form to your feet after a few wears. Most customers buy their regular size but if you have wide feet, we recommend going up half a size. Bonus: our shoes are unisex, with men’s and women’s styles offering the same fit. This means sizes can be converted to suit a wider range of people. Men’s sizes are 1 full US size smaller than women’s. For example, if you are a women’s US 10, you can also purchase a men’s US 9 for a perfect fit.
