Thank you for viewing. This is the FuelCell Speedrift, a collaboration model between New Balance and AURALEE. The model number is NBJ-1079160, the color is gray, and the size is 27cm. I have worn them a few times, but I haven't had many opportunities to wear them, so I am selling them. There is some wear and tear, but there are no noticeable scratches or stains, and I think they can still be worn. The soles are not very worn, and the cushioning is still sufficient. The simple and easy-to-match color makes them perfect for everyday use. Please feel free to comment if you have any questions! Instant purchase is OK. Thank you. □Brand/Model New Balance × AURALEE Collaboration FuelCell Speedrift (Model Number: NBJ-1079160)
