The STK-1: The Gold Standard of Squat Shoes
We are proud to announce that the STK-1, inspired by Yusuke Satake, two-time World Games Champion, has officially been patented in Japan. Our next step is expanding patent recognition worldwide.
Lifters in Japan who have already switched to the STK-1 are sharing incredible results:
• “Just by changing to the STK-1, I added 10kg to my personal record.”
• “It feels so much easier to squat.”
• “Back steps are lighter and smoother.”
• “I can plant my feet firmly without hesitation.”
With such overwhelming feedback, we’re excited to bring the STK-1 to the global stage.
✨ International sales begin today.

Starting today, pre-orders for the STK-1 Lifting Shoes, the signature model of two-time World Games Champion Yusuke Satake, are available on our Japanese online store.
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.
International pre-orders are scheduled to begin in September.
Push your limits and set new personal bests with the STK-1.

To all athletes affiliated with USAPL and IDFPA,
Thank you for your continued support.
We regret to inform you that our ONI Knee Sleeve PRO will no longer be permitted in IPF competitions as of August 18.
However, it remains fully approved for use in official competitions hosted by USAPL and IDFPA.
This applies not only to the knee sleeves, but also to our other gear products.
The ONI Knee Sleeve PRO is known not only for its rigid fabric and excellent rebound, but also for its unique classification system based on weight. Each sleeve is individually weighed during inspection, and even within the same size, products are categorized into three ranks based on weight: SS, S, and A—from heaviest to lightest.
A heavier product in the same size category indicates higher fabric density, which leads to more consistent performance across stiff-type knee sleeves and minimizes manufacturing variability.
Sleeves with higher density rankings provide greater stiffness and rebound, offering enhanced support during training and competition.
Please note that due to their popularity and rarity, products in the higher weight ranks may be priced slightly higher.
Additionally, the weight difference between the left and right sleeves is controlled to within approximately 10 grams, minimizing performance discrepancies between sides.
Although there are currently no USAPL or IDFPA affiliates in Japan, we encourage athletes belonging to these organizations overseas to consider the ONI Knee Sleeve PRO as a new, high-performance option.
We are also actively seeking distributors and brand ambassadors with proven competitive achievements.
If you are interested, please apply using the link below.
(Note: Ambassador applicants are encouraged to obtain a recommendation from a distributor whenever possible.)
Thank you for your attention and continued support.

ONI Lever Action Belt PRO (IPF ID: 319)
We are pleased to announce that international sales will commence next week.
A New Generation of Lever Action Belt with a Carbon Fiber Lever Buckle
This belt represents a significant upgrade from conventional lever action belts, designed for lifters who aspire to set new records.
Wide Buckle for Enhanced Intra-Abdominal Pressure
In squats and deadlifts, greater intra-abdominal pressure stabilizes movement and enhances power output. To achieve stronger pressure, the buckle must provide superior fixation. A wider buckle secures the belt more effectively, allowing for increased intra-abdominal pressure.
Nine-Pronged Structure for Superior Stability and Adjustability
Simply widening the buckle does not necessarily enhance performance beyond conventional wide buckles. To maximize fixation, we have reinforced the prongs, adopting a three-row, three-column (3×3) structure. Users can select from three configurations—three-pronged, six-pronged, or nine-pronged—to adjust intra-abdominal pressure according to the weight being lifted. In its nine-pronged configuration, the buckle delivers fixation strength that surpasses traditional wide buckles.
Lightweight Materials to Offset the Drawbacks of a Wide Buckle
While a wide buckle is essential for generating high power output, its increased volume also results in added weight. Since the lever buckle is positioned in front of the belt, this additional weight can shift the center of gravity forward during movement. To mitigate this issue, we have adopted lightweight carbon fiber, reducing unnecessary strain and enhancing performance.
Smooth and Refined Tightening with a Carbon Fiber Buckle
Unlike conventional metal lever buckles, our carbon fiber buckle offers a subtle yet refined resistance when tightening. This slight elasticity creates a superior tightening experience that metal buckles cannot provide.
Seamless Pin for Durability and Safety
The rotational pin, a crucial component of the lever mechanism, is securely enclosed to prevent detachment due to wear over time, ensuring long-term durability and safety.
