Women's Air Max Portal - White/Pure Platinum Transport your style with a new Air Max. The Portal is the perfect blend of chunky and sleek, combining the platform sole of 2000s with the minimalist upper of contemporary designs. We added an oval-shaped midsole with cloud-like cushioning for an elevated look you can wear every day. It's so comfortable it's out of this world. DETAILS: Quilted material feels plush and looks sleek. Thick foam midsole with visible Nike Air cushioning in the heel adds just enough height. Rubber outsole gives you durable traction. Design details such as the quilted upper and tread take cues from '00s running models.
