Crocs makes Crocs that don't look like the original style.

Not sure why no one has simply taken the cushy sole of Crocs and put a less ugly top part made of normal fabric.

That's basically what Heydudes are.

Oofos have some exactly that except I find them to have far more comfortable soles.

The are quite expensive though.

I do this. I bought the canvas dock style crocs awhile back and when the canvas gave up I notice the insole was removable. I put these in my Cat work boots and they are the most comfortable workboots I have ever had. Why Crocs doesn't sell their insoles alone I will never understand. Thats their biggest best part.
