The uppers are made of suede. They are not cheap. They are available in sizes UK 7 - UK 9. They are being sold at auction by sports outlet on eBay, who have excellent feedback, and also have many other great pairs of trainers for sale, including other pairs of Adidas Samba. Be sure to check out their other items.
If all the links above show the item is no longer for sale, check out this link [Green & Orange Adidas Samba Super] which shows the entire list of this specific colourway. I'm sure you'll find a pair there, hopefully in the size you need. Goodluck.
