adidas Ultra Boost 3.0 Core Black-Dark Grey

adidas continues to show that the design possibilities for the Ultra Boost 3.0 are absolutely limitless. 2017 brings us yet another Triple Black version, this time with a few slight modifications. Released among a trio of colorways that hit retailers on March 31, the shoe features woven Primeknit construction, with the upper sporting a black colorway. The upper is accented by silver streaks in a heathered look, despite Triple Black nametag. The remainder of this Ultra Boost 3.0 is essentially uniform, as black colors the Three Stripes branding on the caging system and the heel cage, Boost midsole, and inner lining.

As every brand has slightly different sizing standards, we advise you to get in touch with the specific manufacturer (e.g. Nike, Adidas etc.). They can guide you to the appropriate size for you. They might also assist with gender size conversions.

Certain trainers might have the sizing type abbreviated next to the name. If there's an abbreviation by the name, it doesn't follow traditional men's sizing. For example, a 6 in GS isn't the same as a 6 in Men's.

• (W) - Women
• (GS) - Grade School
• (PS) - Preschool
• (TD) - Toddler
• (I) - Infant
• (Infant)
• (Kids)

Use this for reference, and you can be sure that you’re ordering the right shoe size for your use case!

Note that different brands and manufacturers size slightly different – so a size 8 Nike Air Jordan shoe might fit differently than a size 8 Adidas shoe, for example.
