Thank you for viewing. This is a Nike Alphafly NEXT% in size 26.5cm. I received two pairs from an acquaintance about 3 or 4 years ago. I don't have many opportunities to wear them, so I'm offering them for sale to someone who needs them. According to my acquaintance, the running distance is about 100-150km. The air units are not collapsed, and the outsole still has some life left, so I think they can still be used for races and interval training. Please understand that there is no box or shoe bag, and they have been stored personally at home. Type: Running Shoes Gender: Men
