Out of the blue Concepts is dropping their next collaboration. A busy year already, Diadora has not yet worked with the Boston-based boutique. Diadora is also one of the biggest up and coming brands in the market for runners. In honor of the Italian currency, this collaboration is based on the Italian 500,000 bill, similar to the concept for the C-Note and the Mint 998’s. Clearly inspiration elicits this new collaboration with hits of salmon, off-white, green, yellow, and blue. Look out this weekend on cncptsintl.com and only Concepts Cambridge (New York is going under reservation), for a retail of $205.
