how do you avoid funny tan lines on your feet otherwise? Last summer I tried avoiding flip flops (I developed a foot pain after spending virtually every day in havaiianas 2 years ago, that only went away after 3-4 months) but I ended up having a 'gladiator' tan on my feet - and I spend most of the day outside with my toddler.. Is there a flip flop style sandal that's stylish for casual MOTG look that won't chew up my feet, or are they all NAY?
