The Adidas Ultra Boost Shoes change everything you think you knew about what fast, cushioned and comfortable feels like. They have boost™ foam in the midsole that has an incredibly responsive ground feel and keeps its form even in the coldest weather. Replacing the Adistar Boost as adidas' top of the line stability running shoe, this shoe is suited to those runners looking for unparalleled comfort while retaining some stability and support for overpronators.
