Unfortunately have to give these up do to sizing. I thought I could a 10.5 but they feel just slightly too big for my liking for a marathon shoe. They have 36 miles on them and just a couple scuffs at the bottom on the paint. I would prefer trading for an Alphafly 3 Sz. 10 worn (less than 30 miles) or new could add alittle cash if so. Maybe another carbon shoe Sz 10. Or if wanting to buy please DM me.
