Please note that in order to avoid stains on the shoe upper the soles are not glued all the way to the edge. The soles are therefore properly glued, and the small gap at the edge of the sole is not a manufacturing defect. With use the gap may become more obvious because the sole of the barefoot shoe is flexible. However, it doesn't mean that the sole is deattaching, there is no loss of function and therefore these cases are not considered as claims.
Always make sure the shoes are proper fit before wearing them. Shoes that are used outdoors can't be returned.
Please note: The materials and stitchings of the shoes will wear out and eventually break if the shoes are used in activities such as balance biking, football etc, or if kicked/rubbed against the ground repeatedly.
