This is "Men's Mega Push - Fumippa & Hardcore." It has an insole like a bamboo footrest to loosen up stiffness in the soles of your feet and improve circulation. It loosens up stiffness in the soles of your feet and improves circulation. Size: 25.5-27cm. I took it out of the box for the photos. It's been in the box since I bought it. I'm listing it as "Like New," but it's a completely unused item stored at home. You can wear it comfortably. I will send it in the box as is. Thank you for looking.
