TENTIAL Co., Ltd. (Location: Shinagawa, Tokyo; CEO: Yutaro Nakanishi), a company dedicated to creating a health-forward society through its conditioning brand 'TENTIAL', will release two new types of sandals, 'Recovery Sandal Flip Flop' and 'Recovery Sandal Pro Flip Flop', on Monday, April 27, 2026, to support foot health during the upcoming warmer season.
In supporting 24/7 conditioning, TENTIAL believes the foot is the foundation of the body, and impairment of its function can affect posture and walking. Therefore, the brand offers products that support conditioning from the feet up. Since its launch in 2021, the 'Recovery Sandal' series has expanded its lineup based on customer feedback, with a major update in the Fall/Winter 2025 season. Cumulative sales have surpassed 220,000 pairs as of February 2026.
In the recovery sandal market, products from foreign brands dominate, and since many are designed based on Western foot shapes, they do not necessarily fit Japanese feet. Furthermore, traditional single-layer EVA sandals faced challenges in balancing softness and stability, with customers reporting that while they were soft and comfortable, they caused fatigue during long walks, or that while they felt stable, they lacked sufficient cushioning.
To solve these issues, TENTIAL spent approximately three years developing a unique footbed design utilizing foot shape data from about 400,000 Japanese people and a specialized sole structure made of carefully selected EVA materials.
The 'Recovery Sandal Pro Flip Flop' being released this time features a footbed design based on this massive dataset, combined with a dual-layer EVA structure to achieve both 'instant softness upon wearing' and 'stability when walking.' By increasing the thickness of the footbed part to allow for deeper sinking when stepping down, the structure makes it easier to feel the softness of the foot strike.
The 'Recovery Sandal Flip Flop' is a model that achieves optimal fit for Japanese feet. Items such as heel position, arch position, height, and length were analyzed in 1mm increments to extract data closest to standard Japanese foot shapes. This analysis is reflected in the shape of the footbed. Available in four colors, the design blends into daily fashion for the upcoming season.
TENTIAL will continue to expand its product lineup to support the conditioning of more people in the future.
Product Summaries:
Recovery Sandal Pro Flip Flop
As a high-end model pursuing the three elements of 'cushioning,' 'fit,' and 'stability' required for recovery sandals, it adopts a dual-layer EVA structure. Low-hardness EVA is used for the footbed for immediate softness, while higher-hardness EVA is used for the outsole to ensure stability during walking.
Recovery Sandal Flip Flop
Utilizing a footbed shape based on 400,000 Japanese foot profiles and an outsole structure selected through several patterns of verification, this model improves ease of walking and stability. The unique EVA blend provides just the right amount of firmness to prevent excessive crushing, balancing cushioning and stability. With a simple design, it offers color variations like Pink and Coral Pink, making it accessible for women as well.
