Designed in collaboration with Undefeated, the Undefeated x Air Max 90 White Solar Red brings a vibrant two-tone look to the classic runner. The shoes upper is built with full-grain leather, finished primarily in white but accented by Solar Red on the tongue, heel and mudguard trim. Underfoot, the midsole houses the usual visible Air in the heel for cushioning, with a waffle outsole providing traction.
