The exact period of use is unknown. No box. Will be shipped in simple packaging. Washed in a household washing machine. The laces have been replaced with gradient-colored ones. Cushioning is sufficient. The insole is glued in and could not be removed. No tears. I usually wear a standard width 26cm in GELBURST and GELHOOP, but these shoes felt a bit tight in the width.
