The Nike Air Zoom Alphafly NEXT% 2 is a running shoe with a lightweight mesh upper and a highly responsive sole. My elementary school daughter, who runs track, wore these in competitions. She used them in about 10 competitions, mainly for 1000m to 2000m races. I am selling them because she has outgrown them.
