Discussion Polyurethane Soles Crumbling: Walking Cradles, Ecco, and Others

[TimelessTraveler]

I loved Walking Cradles until I had two pairs, several years apart, suddenly crumble while I was wearing them. It was such a disappointment, especially since they were comfortable and stylish. Has anyone else experienced this with Walking Cradles or other brands like Ecco? I'm curious if this is a common issue with polyurethane soles and if there's a way to prevent it or if I should just avoid these brands altogether for travel shoes.
