Mizuno Spark 4 Women's Running Shoes

With a balanced and cushioned feel, this neutral shoe delivers optimal comfort on every run.

AirMesh Upper

Airmesh uppers will encase each foot in breathable comfort. The perforations in the mesh allow air to fully permeate the entire construction, providing a constant supply of fresh, cool air. Simultaneously the upper forces out hot, muggy air and keeps the environment in the shoe healthier for your feet. In addition, a mid-foot overlay system wraps around the heel and integrates with the laces to enhance the fit and feel of the upper. This construction provides structural integrity as well as keeps your foot locked-in thus preventing in shoes slipping. A padded tongue, heel and collar increase comfort especially during longer runs, keeping the ride as enjoyable and as comfortable as possible. Lastly, the upper features a premium insock which is a high-grade removable insock for additional comfort and cushioning.

Wave Midsole

Mizuno's wave technology is embedded into the midsole to provide flexibility in one direction and support in the other. The midsole technology works to absorb the shock of heel striking without compromising the comfort or cushioning. Once the shock has been absorbed the energy from that is harnessed and is then transferred to the forefoot to then push you off and guide you onto the next movement. The wave prevents partial deformation and provides dynamic support to stabilise and guide the foot forward. U4icX absorbs impact for the smoothest ride possible. For additional comfort, the unique compound, U4ic is used in the midsole which rides and cushions like Mizuno's AP+ midsole but is approximately 30% lighter without any loss of comfort or performance. Finishing off the midsole is Mizuno Intercool which is a full-length midsole ventilation system to reduce heat and humidity build-up inside the footwear. This helps to improve the atmosphere when running, lessening the distraction or discomfort provided by hot air.

X10 Outsole

The midsole and outsole technologies work together with SmoothRide technology to provide a fluid, rocking-chair-like transition. As the foot hits the ground, SmoothRide Engineering kicks in with heel flex grooves promoting a natural back-to-front movement. The forefoot flex grooves and flex controllers then work together to continue the smooth forward motion resulting in an efficient fluid motion that allows runners to harness their power. The outsole is made with X10 which is the most durable carbon rubber that allows for longer wear in high impact areas and supplements traction at heel strike. This helps to lessen the impact placed on the knees and joints, allowing for a more comfortable ride as well as optimising gait efficiency. The outsole also ensures maximum grip and traction for a firm, assured footing so you can run with confidence and push yourself to the limit, time and time again.
