Size and fit

The Asics Cosmoracer MD, although available in men’s shoe sizes, it is a unisex track and field shoe. Women users are suggested to go 1.5 sizes down from their usual shoe measurement to get their right fit. The Cosmoracer MD is also known to have a medium to narrow heel and a toe box that runs medium in width. Despite these suggestions based on online reviews from other users of the Cosmoracer MD, it is still advised to get the best fit by visiting one’s nearest running specialty shop to get an accurate measurement.


The Cosmoracer MD’s outsole uses the Pebax Spike Plate on its outsole. It is designed with a decoupled polymer plate, and it is strategically placed in the forefoot for lightweight flexibility and stability. The Pebax Spike Plate is also strategically designed to provide the shoe its rigidity and power. A similar spike plate could be found in the Nike Zoom Rival M 9.

The shoe’s outsole contains four spike receptacles per shoe for optimal traction and control.

Working in unison is the SharkDuo technology, which is found in the heel area of the shoe. It is a textured thermoplastic unit for increased grip on various track surfaces.


The shoe's midsole is incorporated with a Solyte foam, which is a full-length midsole material for increased energy return and responsive underfoot cushioning.

It helps improves the shoes' bounce-back abilities and also helps in decreasing midsole breakdown. This, in turn, offers a cushioned platform to ensure efficiency at high speeds.


The upper construction of the Asics Cosmoracer MD is made with a lightweight mesh material that is responsible for the shoe's breathability. It lets in the fresh air, allowing it to permeate the interior, keeping the foot cool and comfortable as the wearer runs down the track.

Integrated alongside this feature, is the seamless overlays. These overlays create a more snug and comfortable fit for lightweight performance. It also helps in locking in the foot in place for a secure fit and feel while acting upon torsion to maintain the shoes' shape and form.
