Nike Infinity React Flyknit running shoes

These are gently used running shoes in great condition. I’m selling them for my sister who said they didn’t fit right. I am not sure which edition these are, but here is Nike’s description of the shoe on their website: A Secure, Breathable Flex We added Flyknit throughout the upper, creating specific zones of breathability, flexibility and containment. The result is a cool feel that helps your foot feel secure, while letting it move without restriction. It still has Flywire technology for support through the midfoot. Smooth and Steady The sole has a unique rocker design that's shaped for support during all 3 phases of your stride. It feels flexible when you push off the ground, has a smooth ride when your foot moves forward and cushions when you land. Nike React technology provides that soft yet responsive sensation at every step. The bottom is wider for more stability on contact. Cushioned Feel, Higher Stacks High-rise cushioning is placed directly under your foot so you're closer to the foam for a truly responsive experience. Hybrid tongue combines a sock-like feel with the adjustability of a traditional design. Soft padding along the collar provides a cushioned touch point. Increased rubber at the outsole gives traction and durability.
