The adidas Yeezy Foam Runner 'Sulfur' features a beige hue throughout the one-piece EVA foam construction, with strategically placed vents throughout the instep and side panels for maximum breathability. Inside the slip-on, the insole is equipped with a textured surface that prevents the foot from slipping. Branding is limited to 'FOAM RNNR' embossed on the inner collar and an adidas logo on the contoured outsole, which features a rippled traction pattern for optimal grip.
