ASICS trainers generally follow standard sizing. If you have worn ASICS before, use the same size; otherwise, ensure there is about a thumb's width of space between your longest toe and the front of the shoe.

The tread pattern is highly effective on artificial grass and synthetic court surfaces commonly found in padel centers.

For active players, it is recommended to replace them every 6-9 months depending on the intensity of play and signs of outsole wear.

Check the outsole for dirt or sand accumulation; wipe with a damp cloth to restore grip.

Use the 'runner's loop' or 'lock-lace' method with the top eyelet to secure the heel.
