I am in my mid 50s. I could wear any shoe without pain. Now that I am older, I have to make sure my sandals and shoes have support since I am flat footed. I have so many different type of sandals and flip flops, all stating they support your feet. At the end of the day, my feet ache and my hips hurt! When I read about Olukai and the reviews, I thought I would try them. So far I LOVE them. They do not look like orthotic flip flops. They have a strong arch support and I don't hurt after wearing them. The only other sandals I love are Birkenstocks, but they can't be worn near water. I know these are expensive, but they are worth it!!!
