Troubleshooting
Fit feels too tight
Try wearing thinner socks or consider a half-size larger if available. The Primeknit upper does offer some stretch over time.
Tread wear on the outsole
Ensure you are using the correct trainers for the intended activity. Using running shoes for aggressive court sports can accelerate outsole wear. Clean the outsole regularly.
Discoloration of white elements
Clean the white areas promptly after exposure to dirt or staining agents using a mild soap and water solution.
