Worn a few times, I got the wrong size but they are super comfortable! Details The GEL-QUANTUM LYTE™ SLIP-ON shoe is inspired by the evolving design language of the GEL-QUANTUM 90™ sneakers. Constructed with a breathable mesh upper and a stretchy back heel formation, this shoe also features a wrap component across the forefoot to match the silhouette's tech-focused aesthetic. This shoe's tooling draws functional design references from our performance running styles. Additionally, its rearfoot GEL® technology helps provide good shock absorption and a soft feel underfoot.
