The Yonex Women’s FusionRev 4 Tennis Shoe are a refresh of the FusionRev. The Yonex Women’s FusionRev 4 Tennis Shoe remains the perfect shoe for players looking for the ideal blend of support, cushioning & speed. Like version 3, Yonex designed the Women’s FusionRev 4 Tennis Shoe with a bootie construction upper with the “Fusion Wing” that locks your foot in on the court. Yonex continues the use of “Power Cushion +” in the midsole for an even smoother ride out on the court. Yonex reconstructed the outsole with an Endurance Rubber compound in a zonal tread pattern which helps with durability. Yonex pull-tab on the tongue.
