Thank god I found these shoes. I had to replace the spikes he got to start the season after first meeting. The bottom of the other shoes came off in the middle of the treadmill. I had to use duct tape to hold them together so he could end the meeting. These shoes are well made and work great. My son has used them for the 110m and 300m hurdles, mileage relay, long jump and pole vault with no problems. After 6 encounters on the track and 7 weeks of training, they still look like new.
