These are a great barefoot boot, zero drop and wide toe box. They do have a thicker sole but they are truely barefoot and are very flexible and lightweight weight. Real leather her uppers and rubbery soles with wool inside and side zip closure and laces for perfect fit. They are European size 42 which is like 10.5- 11 American. Wore a few times but the tread is still almost perfect despise the tops looking a little wrinkled from being in a box for awhile.
