These are new old stock, I bought these and apparently forgot them in the back of my closet. Feel free to make an offer. Upper: They feature a Threadborne knit upper designed for a breathable, compression-like fit that offers lightweight strength and flexibility. Cushioning: The shoes utilize a two-piece Charged Cushioning system, which pairs a soft top layer of foam with a denser layer of foam for both comfort and support. Outsole: The durable rubber outsole is segmented with flex grooves to provide traction and flexibility during your stride. These shoes were designed as a running shoe, providing a balance of flexibility and cushioning for runners who need a versatile trainer. They generally fit true to size.
