Inspired by the anatomy of the foot and the elegant curves of the Ionic Spiral, this design embodies balance, growth, and harmony.
Prevention of foot slipping with 6 anti-slip grooves etched into its surface. The grooves are inspired by dividing the 24 flutes (grooves) of a classical Ionic column into equal parts. Blending mathematical precision with architectural beauty.
A robust lower base designed as the product’s strong, unwavering foundation for maximum stability.
Inspired by the axial neck rotation, this clip enables seamless pad rotation, offering versatility across different exercises variations and platforms.
This clever feature also enables the Talus Arch to rotate from the Sup’r Stratum without having to remove the entire equipment off a platform. This is accomplished by lifting the pair of indentations on opposing sides.
Inspired by the Ionic Capital’s Balteus, a metaphorical belt of unity and strength, this securing belt is crafted from robust materials and features an exquisite striped design in black, coyote, burgundy, and deep teal.
The straps echo the timeless tones of ancient Olympia. The Cayote (gold) represents the radiant hues of the ancient games, while the other shades reflect the serene landscapes of Greece.
Inspired by Fascia, the connective tissue that binds our organs, blood vessels, bone, nerve fiber and muscles, our durable anti-slip material at the base provides secure grounding on surfaces. This lets you focus entirely on your performance and keeping your focus where it belongs: on your training.
