GEOX pumps, new and unused, only tried on at the time of purchase. They have been stored for several years, but there is no stickiness on the resin parts. Size is 36, equivalent to a Japanese size 23 cm. They are a bit narrow, but I usually wear a 23 cm with an E width, so they might be about the same or slightly narrower. I plan to wrap the box in bubble wrap and paper for shipping. Please understand. I have a cat, so even though I'm careful, cat hair may get mixed in.
