Both men and women are likely familiar with flip-flop pain. A solid walk in flops through Boston Garden after a six-month winter in boots will either require a foot massage or time in a hot tub. Shroyer's research offers plausible explanations for the source of such pain. However, after 196 consecutive days in flops, most men could run a marathon in their favorite pair of Rainbows in under three hours. So is it wearing flops, or taking a break from flops, that leaves one writhing? As a native Floridian and current Californian, I'll pray for the latter.
