The biggest feature is that it uses a thicker cup insole than before, adding cushioning.
Like traditional Spingle insoles, the insoles are made of "latex sponge," the same material used in cosmetic puffs, and are characterized by their high resilience and softness.
In addition, the arch is supported by inflating the arch, providing a high level of fit, cushioning, and stability.
*The images below show the new cup insoles as samples to make them easier to understand. The color of the cup insoles that actually fit into the SPM-1020 will be beige, just like the conventional product.
