ASICS GEL-Resolution Tennis Shoes

The GEL-Resolution X is the current successor to the GEL-Resolution 9. Key updates include DYNAWRAP technology for improved midfoot lockdown during lateral movements, a refined outsole tread pattern with larger lugs for better hard court grip, and FlyteFoam cushioning that reduces weight while maintaining the support the line is known for. The overall construction is lighter by approximately 0.5 ounces without sacrificing durability.

Both models run slightly long. Most players size down a half size from their usual length. The GEL-Resolution X also has a roomier overall volume compared to the 9, so players coming from the 9 who prefer a snugger fit may want to try the X before ordering or consult our fit team.

Wide (2E) widths are available in select men's colorways, offering approximately 0.25 inches of additional room through the forefoot and midfoot. Women's wide options vary by model and are typically limited to core colorways. Check individual product pages for current wide-width availability, as inventory updates regularly.

Yes. Clay court versions of the GEL-Resolution use a full herringbone tread pattern designed for controlled sliding and natural clay release from the grooves. This allows confident lateral slides and clean push-offs without clay buildup affecting traction. Players switching from hard court shoes to the clay court GEL-Resolution typically notice improved slide control and better baseline stability. For hard courts, AHAR Plus rubber in high-wear outsole zones handles the abrasive surface and is backed by ASICS' 6-month outsole warranty under normal playing conditions.
