So NM is sending my other Gucci shoe out tomorrow lol so I'll have a complete pair. The only thing is that the bottoms of them are wood with stitching around the outside. They don't look very durable for walking around outside in. How do I get treads or non-skid bottoms put on them? This is the first time I've needed to do this. There's a local cobbler but I'm not sure I trust them with my shoes. How do you make sure they won't ruin your shoes? What questions should I ask?
