Sticky grip

The bottom of the Ryka Hydrosphere is lined with sticky rubber. It is meant to render grip on a variety of wet surfaces.

Ryka Hydrosphere Outsole1

Parting the rubber are the flex grooves. They make sure that the platform bends easily with the foot throughout the training session.

Ryka Hydrosphere Outsole2

The front portion of the rubber outsole extends up to cover the toes. It creates additional protection against bumps and abrasion in this part of the shoe.

Cushioning and drainage system

The Hydrosphere employs the CMEVA foam for cushioning. It is made to be lightweight and pliable to accommodate active foot movements.

Ryka Hydrosphere Midsole1

Several large perforations are placed throughout the unit. They are part of the multi-port drainage system which helps in removing water from the foot chamber. 

Ryka Hydrosphere Midsole3

The Nitracel footbed is added on top of the midsole inside the shoe. It is perforated to assist the water drainage, but it is still made thick enough to prevent debris from getting inside the trainer.

The Ryka Hydrosphere's upper

A breathable knit material is used to deliver a sock-like fit. It holds the foot securely when the shoe is on but stretches easily whenever it is needed throughout the movement. The brand also claims this material to be quick-drying and resistant to damage from chlorinated water.

Ryka Hydrosphere Upper1

The upper is constructed with a round toe to offer extra space at the front. It allows the toes to splay and wiggle freely inside the shoe. 

Ryka Hydrosphere Upper2

Inside, the trainer is lined with soft fabric. It contributes to the comfort and prevents chafing.
