Nike Zoom Vaporfly Elite - it was with the same model of shoes that Kipchoge ran the 2017 Berlin Marathon in an epic battle against debutant Guye Adola and ran the 3rd fastest marathon ever at the time in 2 hours, 3 minutes and 32 seconds. Signed by Kipchoge and tailor made for Kipchoge (which usually is the case for the top 10 marathoners).
