Thank you for viewing my product. 【Brand Features】 MBT is a brand known for its design that considers the health of the body. Its unique sole structure reduces stress during walking and supports a natural posture. MBT's unique curved sole replicates the natural instability of walking barefoot on the ground. This creates a moderate rocking motion while walking, which can improve posture, boost basal metabolism, and provide core training benefits. I purchased these about 7-8 years ago on the recommendation of a friend, but I haven't had many opportunities to wear sneakers, so I only wore them for two walks around the neighborhood and then stored them. I could really feel my body's center of gravity lifting, and I could feel myself using my feet to move. It's a shame to let them go to waste, so please, someone, use them. Simple light gray lace-up sneakers, perfect for casual style. - Color: Light Gray - Design: Lace-up - Sole Material: Rubber - Style: Casual Thank you for looking.
