As a year-round flip-flopper for many years now, those clips of shoes rocking sideways under pressure are nerve wracking to look at. Most (all?) shoes are terrible ankle hazards. Never have I twisted my ankles with flip-flops.

Considering this article is about running shoes, I have to ask - you run in flip-flops?

I think flip flops would perhaps be a mistake, but very close: huaraches, or strappy running sandals, are demonstrably applicable to distance running.
