old dog needs climbing shoes

I need old rock climbing shoes, any condition, any size, for a sweet 16 year old dog who is going lame in the hind legs. She has trouble getting up on the wood floor, her stiff legs slip all over. (can't have carptet, she's also incontinent) I'm thinking to fashion her some non-slip booties (commercial booties not traction enough) Yes, it's an experiment, but hoping to make her last days a little more comfortable. If you have some tattered nasty old otherwise useless shoes to donate, please email me.
