Product Details
＋This year Adidas has expanded its range of mass market trainers to cater for runners who want a shoe that’s kind of an Ultraboost but just a little bit different. If you think of the Ultraboost as being at one end of a spectrum and the SL 20 at the other, the Ultraboost PB is in the middle. A bit lighter, a bit faster, but not drastically different.
