ASICS GEL-Nimbus 21 Fit
The 21 looks similar to the 20 right out of the box, but a close look at the mesh upper shows some differences.
ASICS says it used an all new engineered mesh upper to make the shoe more breathable and more supportive. Inside, a molded EVA sockliner conforms to your feet for a comfortable fit.
One Fleet Feet wear tester said the first thing she noticed was a plush, padded heel collar and tongue that made the shoe immediately comfortable. ASICS’ external heel counter provided a secure fit, and the width was comfortable even for wider feet.
The toe box is wide enough to accommodate an array of foot shapes, but one tester said she would have liked a bit more height to be able to lift her toes.
