These are canvas shoes from HOBIBEAR, a long-established brand of barefoot shoes (though the name seems contradictory). They are made of black fabric with a slightly reddish-brown natural rubber sole. My foot size is about 27cm, and I wore them for a day, but they were still a bit too big, so I'm selling them. *Worn with thin socks. The dimensions, measured from the inner sole, are 27.8 x 9.7 cm (see photos). Also, they are excellent for those who are prone to bunions, like myself!
