The 2000s saw a decade of experimentation in trainer design, and these adidas Astir Shoes bring it all the way back around. Inspired by performance and materials, they wrap synthetic overlays on a closed mesh upper for support and style. Exaggerated eyelets punctuate the look. You'll get responsive energy with an EVA midsole, plus extra traction and grip with a rubber outsole. Made with a series of recycled materials, this upper features at least 50% recycled content.
