Rakutsu RIO Fall Risk Reduction Shoes 22.0 to 22.5 cm Ships in the original box. (There may be initial scratches on the outer packaging. Thank you for your understanding.) The regular price is around 6,000 to 6,500 yen (depending on the sales location). More gently, more accessibly. The Rakutsu series is designed under the supervision of a US podiatrist so that many people can continue to walk longer, more enjoyably, and more comfortably. This pair is made with the hope that it will enrich everyone's daily life and add color to their everyday lives. Falls and tumbles caused by footwear account for 38.5% of all cases, or about 4 out of 10 people. Falls and tumbles are a major cause of needing nursing care. (*) Rakutsu is designed to significantly reduce the risk of falls while walking. With its unique technology, it enhances stability and firmly supports the feet. *Source: Tokyo Kurashi WEB 【POINT 1】 Design that prevents sideways falls The flared sole increases the ground contact area, increasing the load resistance in the sideways direction. It also suppresses lateral center-of-gravity sway (unsteadiness). 【POINT 2】 Design that prevents inward collapse The heel counter of Rakutsu is hard and longer on the inside. By firmly supporting the calcaneus, it prevents the foot from collapsing inward and also suppresses center-of-gravity sway (unsteadiness). 【POINT 3】 Difficult to trip As people age, it becomes more difficult to lift their feet when walking. Rakutsu has a design where the toe part is moderately raised, making it difficult to trip and allowing for smooth weight transfer.
