Hi Dakota and Curious.

He has crocs but he loves the slip on slippers.

I have velcro. I'll just sew a piece of stretchable elastic on one side and put some velcro on the thing, and on the other side I'll put the other velcro thing.

VOILA!!!

We will have a shoe that he can slip on and then fasten to his liking.

You guys are good.

Much thanks,

Melody
