STK-1 The Gold Standard of Back Squat Shoes
The STK-1 combines the sensory benefits of barefoot lifting with the rigidity required for maximal load transfer, creating a new category of squat-specific footwear.
Ultra-Wide 8E Toe Box
Exceeds conventional wide-toe designs, allowing natural toe splay and delivering a true barefoot feel inside the shoe. This improves force distribution and stability.
8mm Heel Drop with Gradual Pitch
Engineered to maintain ideal ankle dorsiflexion, keeping the barbell aligned over the midfoot—the body’s natural center of gravity—throughout the lift.
All-Flat Architecture
By removing arch support inside and outside, the STK-1 provides a flat platform. This reinforces barefoot mechanics while enabling lifters to stabilize maximum loads at depth.
Patent-Pending Carbon Plate System
Combines high rigidity and rebound with controlled flexion at the MP joint, producing efficient propulsion and smooth backsteps without loss of power transfer.
These innovations were decisive in Yusuke Satake’s back-to-back World Games victories. Until now, squats were performed in repurposed weightlifting shoes. The STK-1 overturns this convention as the first footwear engineered solely for squats, offering greater specialization and biomechanical precision than adapted designs.
The STK-1 establishes a new gold standard in squat footwear. Its effectiveness spans world record contenders and beginners alike. By uniting advanced engineering with the demands of competition, it ensures measurable gains in stability, efficiency, and performance.
