Diadora is an Italian athletic footwear and sportswear brand.

Marcello Daniel founded Diadora in 1948.  In June 2009, Geox founder and chairman Mario Moretti Polegato's investment company LIR purchased Diadora's assets.

Diadora sneakers have not had a significant impact on the sneakerhead market.  An upswing in collaborations for 2014 gains the brand exposure with a new generation of buyers.
