Adidas Ultraboost 21 Sneaker (Black - 9)

(303 reviews)

When the weather turns cold and wet, you still owe it to yourself to get out there. These adidas Ultraboost 21 COLD.RDY Shoes make it easier. The insulated upper sheds water to keep your feet warm and dry. A Continental WinterGrip Rubber outsole keeps your footing secure on steep downhills and slippery stairs. Responsive Boost cushioning gives you an energised feeling that reminds you that you can always go one more step, maybe one more block or perhaps another mile. Sock-like fit. Lace closure. adidas Primeknit+ upper. Textile lining. Supportive heel counter. Boost midsole.
