Luna sandals recommend almost the same size as the actual size of your feet. If you do not know the actual size, if you can afford about 1 cm of the toe in the running shoes, the size is about 1cm smaller. If you wear US9 (27cm) with Altra running shoes and have a 1cm room for your toes, it is recommended to purchase US8 (26cm).

The founder, Ted McDonald, has long been running with the latest running shoes fixed like a cast, for a long time. At one point, I tried to throw those shoes and start running. Then his feet were released, and a pioneer in Bearft Running was born. In the spring of 2006, Barefoot Ted visited a few elite Ultra runners and Mexico in the north. So Ted was a master who made traditional Warci sandals from old tires, and met the legendary ethnic Thamala, Manuel Luna, and taught how to make it and its philosophy. "Luna Sandal" started here
