The Nike Air Max 90 Leather GS 'University Red' is a children's shoe that features an all-red design, giving it a classic yet vibrant look. Unlike the typical mesh base, this shoe utilizes synthetic leather throughout, with only the eyelets and branding made of ribbed rubber. The red material is consistent from the underlays to the overlays on the toe, side panels, and rear mudguard. Additionally, the shoe includes the iconic Air Max logo on the heel, side, and tongue. As with all Air Max shoes, the heel houses a visible Air unit within the midsole, providing cushioning and support.
