Alphax Core Training Slippers Sliet Y-Type for Women Sliet Sliet Y-type Color: Mustard Size: 22.5-25cm Diet, Core Training Health Sandals After ordering online, I only opened the box to check the product and try it on, so it's almost unused. It didn't fit my feet, so I couldn't wear it. [Improve posture by incorporating the basic poses of standing yoga] The basic pose of standing yoga, "Mountain Pose," is a very simple way to stand, but it has the effect of improving posture. Inspired by this, the Sliet Y-Type was created with a unique inclined sole and insole that support the entire sole of the foot on the ground, allowing you to experience a feeling of composure, as if you were doing yoga, just by wearing them. [Beautiful posture just by wearing them] The inclination of the sole makes you conscious of shifting your center of gravity backward, strengthening your lower abdomen, hips, and calves, and naturally straightening your back for a beautiful posture. By strengthening your core, the ability to support the center of your body increases, which eliminates slouching and naturally improves your posture. [Core strengthening with an oblique incline] By strengthening your core, you can expect effects such as improved posture, better appearance of your standing posture, and easier and more stable movement. You can train your core, which is essential in our daily lives, just by wearing these slippers at home. ※ Due to shipping costs, the item will be removed from its box for packaging. Please understand.
