NWT Happy Socks pools slides | 39-40

Pool slides in Rock N Roll Stripe by Happy Socks. Footbed is yellow gold, top is orange with turquoise stripe. From website, footbed is PVC and strap is EVA. Strap has soft felty material on underside. Size 39-40, but I think these fit on the smaller side, closer to a 9. I am a 9.5 and these were a bit too small. NWT, purchased for myself but were too small and I could not return.
