The color is a slightly lighter beige than in the photos. It's a knit material with a bit of stretch, so it should work even if you have a high instep. The size is approximately 24-24.5. I've worn them a few times, but they're in good condition. There's a little bit of dirt on the insole, though it's not visible. Please check the photos, and if you have no other concerns, I'd appreciate it if you would consider them. (^ ^)
