I know they are not the best choice of footwear but flip-flops are what make summer for me. Nothing like the casual ease of having a pair out by each dorwy so I can slide them on and go.
For whatever reason, none of the 15 pairs I have tried feel secure. I have only worn Indian made brands (Bata, Gliders etc.) which seem to be more secure. It makes sense because several (including me when I lived there) wear flip-flops exclusively.
So I want to hear recommendations from committed flip-flop wearers about brands they like for frequent use.
