This is the first-generation Vaporfly. Among the successors, which have reached the 4th generation, the first and second models are highly regarded. There is dirt on the toe of the right shoe from running on an all-weather track (see photo 4). I decided to sell these after organizing my shoes. The running distance is about 20km. #spikes #marathon #trackandfield #ekiden #running #shoes #SuguruOsako #Nike #Adidas #proelite #Vaporfly #Alphafly #Aeroswift
