I live in Florida so flips flops have always been by shoe of choice. I would say for the past 25 years I have been running around wearing flat shoes with no support. Recently I have traded in my flip flops for sneakers. I wanted to start wearing more supportive sneakers. I have been having back issues so my doctor said try wearing sneakers to give your body more support. I starting researching tennis shoes and I can across arch support socks. The brand that I ordered and love are called C3fit. The socks are very breathable and seem to fit my feet perfect.  They run $14 a pair but they last and wash very well.
