I purchased this online from GU. It's new, only tried on once indoors. I'm selling it because the size doesn't fit. GU Ultra Stretch Long Boots Color: BLACK Size: WOMEN M (23.5cm) The sole uses lightweight EVA material despite being thick. The stretchy material provides a comfortable fit even in a long length. The cup-shaped insole that wraps around the heel and arch provides a secure fit. Made with ultra-stretch material. Materials Upper: [09BLACK] Synthetic leather, [88BLACK] 94% Polyester (86% recycled polyester fiber)・6% Polyurethane, Sole: Synthetic sole
