ZETT Corporation (headquartered in Tennoji-ku, Osaka; President: Hiroyuki Watanabe), which handles the ryka brand, has released two new color variations of the aqua fitness-specialized HYDRO SPORT shoes in mid-January 2026. The new lineup features a fresh spring green base and a popular black base.
HYDRO SPORT Features
The HYDRO SPORT is an aqua fitness-specialized shoe with the following features:
- Uses breathable mesh material for excellent water drainage and ventilation
- Full-length shank prevents twisting and provides slip-resistant stability on pool decks
- Shoe lace stopper enables smooth on/off while maintaining a secure hold
- Supports a wide range of activities including aqua dance, aqua fitness, and aqua walking
What is Aqua Fitness?
Aqua fitness is a water-based program where you can achieve more effective body shaping by walking and running in the pool.
The buoyancy reduces strain on knees and hips, while the water resistance allows for high-load exercise.
It also improves blood circulation and cardiopulmonary function, and makes joint movements smoother.
This non-swimming exercise program takes advantage of water's unique properties, including natural abdominal breathing and increased energy consumption.
