I bought Sparx shoe from Amazon shoppe since 2 years ago. I ran 5km, sprint 100.200, 400 meters. Still it is in good condition. A small stitch was taken because of my own risk. I played football with running shoe. A little damage has taken from left side of the part but now it is OK after stitching. Also I bought a new inner sole from sports shop and inserted in my regular Sparx shoe. I feel much comfortable after inserting a new inner sole. I attached my shoe pics please watch it.
