Here are a few things going on on these shoes.

the number 101722 is stamped in silver ink with 12 D following it on the inside edge of the shoe at the place that would be closest to the ankle.
On the inside sole of the footbed where that heel would be is GUCCI with made in italy underneath the m in made and the i in italy are both lowercse letters there is NOT a capital R in a circle above the word GUCCI.
this is all embossed into the material, not stamped with ink,

On the top velcro strap about an inch from the end is GUCCI, made in italy underneath and a capital R in a circle above the word GUCCI again this is embossed into the material
and again on the outside of the shoe near the heel is the same marking as above

On the bottom of the shoe is again is the same marking as above this time the lettering is slightly raised and the sole is covered in tiny raised triangles.

I am trying to get some pics but they aren't working out very well

Thanks again for any help
