I've worn these about three times. The color is gray. It looks like a gray that's close to black, but not completely black. The fastener is Velcro. When mailing, I will put them in a bag and press them down to reduce the thickness. They will be sent via Yu-Packet Post. Please consider purchasing only if you understand this. They are currently stored in the shape shown in the photos. Instant purchase is OK. No price reduction. Please feel free to ask if you have any questions. #Sandals #Boys
