New Year, New Shoes, New UltraBoost.  The Ultraboost is currently one of Adidas’ most popular styles.  Featuring BOOST midsoles for optimal comfort and having a sock-like feel are two of its main selling points.   This new version of the Ultraboost will have that same sock-like feel and one of the thickest BOOST midsoles ever seen on an UltraBOOST.  This year’s model will also have similar lace cage overlays to the 20 model, but these are slit rather than solid, presumably for better airflow and aesthetics.  Like the UltraBOOST sneakers of the past, the 21 model is sure to be a hit.  And to be sure there was a colorway for everybody, Adidas is releasing the UltraBOOST 21 in twenty-four different colorways in men and women sizes.  So far, we know of eight colorways that will come out on February 4th, which you can view below.  Remember to set a reminder on the Adidas.com Release Dates page next month to secure your pair.
