Updates to Ryka Hydrosphere

  • The Ryka Hydrosphere is the second hybrid water fitness shoe by Ryka after the Hydro Sport. Both trainers are designed to accommodate activities that involve water or getting wet. They employ the same midsole unit made of CMEVA (compression-molded EVA foam) for lightweight cushioning. It has multiple perforations, or drainage ports, that assist in removing the water from the shoe. The Nitracel footbed adds padding and ensures that debris doesn’t get through the ports.
  • The upper unit of the Hydrosphere offers a completely new design. It now features a lace-free slip-on construction for smooth on-and-off wear. The knit material hugs the foot in a snug way, but it is also made stretchable for the freedom of movement.

Ryka Hydrosphere size and fit

The Ryka Hydrosphere is available in women’s version only. It is offered in a range of US sizes from 5 to 12, including half sizes. The shoe tends to run on a larger side, so ordering half-a-size smaller may be necessary to achieve the right length and fit. Widthwise, the shoe comes in a B - Medium profile.

Outsole

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

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

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.

Midsole

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

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. 

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.

Upper

This Ryka trainer features a slip-on construction with pull tabs on the instep and the heel collar. It makes the process of putting on and removing the trainer fast and easy.

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.

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. 

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