Usually my feet stray off of flip-flops toward the inside, but the pretty and plentiful straps on these Tevas keep my feet in the correct place.  They're also extremely comfortable - nice and squishy.  Unfortunately, they also turn the bottoms of my feet BLACK and the discoloration doesn't come off easily - it takes some scrubbing with soap and a washcloth.  These flip-flops would get 5 stars if it weren't for that.
