When it comes to Asics tennis, there’s little else as successful as the brand’s Gel-Resolution sneaker line. The most popular tennis product in brand history—and one of the most popular models in the industry—launched its 10th iteration in January, giving the Gel-Resolution X an update focused on comfort and support, the brand says.

A new midsole design includes both Flytefoam in the forefoot and FF Blast Plus Eco foam in the heel, paired with the brand’s signature gel cushioning, meant to improve the underfoot comfort of the model. An updated Dynawall stability feature on the upper now wraps the heel for improved support.

“The comfort and support in this new model are game changers,” says Brazilian tennis player Beatriz Haddad Maia.

Other design tweaks include a higher medial ankle cut meant to support the ankle and a customizable lacing system. Asics launched the model ahead of the Australian Open and features a range of colors for both men and women.
