Purchased at Step Sports. Usage History: * 5km x 3 * 10km * Half marathon The half marathon I last used it for had poor footing, so there's some mud, but please rest assured that the total running distance is low. Selling because I can't use them effectively. #Marathon #TrackAndField #Ekiden #NIKE #Alphafly3 #Vaporfly #adidas #AdiosPro4 #asics #Metaspeed
