I don't think this deserves to be in Style&Beauty 
My autistic 10 yr old loves Crocs. Getting him to wear shoes at all is a massive battle and he basically lives in Crocs in summer and wellies in winter. But, the sole on Crocs is so slippy and dangerous when they're wet that I really need to find an alternative before he slips over one more time and starts refusing to wear them too!
So... like Crocs, but with a decent grip on the sole... Are they a thing? Main requirements are that they are lightweight, dry fast, and can be put on without having to use hands to help them on or fasten them (he won't wear shoes that he can't just shove his feet into and my life is too short to argue over it). I don't really care what they cost because he doesn't go to school and isn't into fashion, so these will be his only shoes (other than wellies) until they wear out.
