This is a Pilates foot corrector, an equipment piece. I thought the American-made ones were too expensive, and since there weren't any domestic ones, I made my own original version. This equipment is specialized for exercises of the feet and toes. It allows elderly individuals and those with low physical strength to easily focus on their toes and soles. The design is based on the Balanced Body foot corrector (centerline model). (The foot plate (the part you push with your foot) has a wider range of motion (front, back, left, and right) than other foot correctors.) It's recommended for the elderly, those with low physical strength, and those with weak foot sensation, rather than athletes. The dimensions are: length 31cm, width (17.2cm (spring section), 10.7cm (foot section)), and the distance between bolts is 13.4cm. The reason for the "as-is" condition is that there is a step on the base (see photo 3) and roughness on the underside of the foot plate (see photos 4 and 5). (There are no issues with use. It's just that the aesthetic quality of the construction isn't perfect.) This is a one-of-a-kind item. From a branding perspective, If it doesn't sell, it will just be discarded. Please refrain from purchasing if you are overly concerned with detail or seek perfection. It will be shipped disassembled. (A 14mm socket wrench and a spanner are required for assembly. Please prepare these for future maintenance.) Please do not negotiate the price.
