Nike Calm, offering a comfortable fit with an adjustable back strap. - Brand: Nike - Color: Black - Sole Material: Rubber - Design: Fur-lined clog sandals - Back Strap: Adjustable Thank you for viewing. I used these once, but the size didn't fit me, so I'm selling them. I just bought them, so they're in like-new condition. Thank you. There was a slight mistake in the description. The color is black, not navy.
