The Air Max 90 Winter PRM is made using a blend of leather and nubuck materials, which are strategically placed throughout the upper. This construction not only enhances the durability of the shoe, but also gives it a more robust appearance, capable of withstanding the harsh conditions of the coldest season. The top of the shoe features a cohesive color scheme in varying shades of grey, creating a visually appealing design. Additionally, the gum outsole not only adds a contrasting touch, but also provides improved traction on slippery surfaces, ensuring stability and safety while wearing the shoes.
