Young woman with high arched feet in flip-flops

While shopping at the mall, I noticed a young woman with high-arched feet in flip-flops. Every time she reached for something on the shelves, she would lift her feet. At that moment, I could see that the leather insoles of her flip-flops were wrinkled and partially peeled, so she undoubtedly had very sweaty feet. On top of all that, she had amazing toes with pink-painted nails.
