La Sportiva Mythos and Petzl helmet

Hello,
I bought a pair of la Sprotiva Mythos climbing shoes online only to find out that they are not my size. I am considering sending them back to the shop but I guess that now that taxes are paid maybe some one would be interested on having them. This is the exact product I bought:

size 43.5

Also had the same problem with a helmet:

Let me know if you are interested.
