The bad and the ugly for all foot types

If you are choosing non orthopedic sandals, but true flip flops here are some things to consider. The construction of the flip flop itself is problematic. The materials themselves are often not of the best quality. They do not have an adjustable enclosure. Flip flops themselves are not typically made as supportive footwear. They do not properly strap onto the foot; by nature they flip and flop, wither as a slide style with a single wide strap across the forefoot, or a thong style with a piece that fits between the hallux (the big toe) and the second toe with two straps making a V over the forefoot. These straps do not secure the shoe to the foot in a supportive way, often causing harmful mechanics that cause cramping and soreness. Flip flops cause the toes to grip, resulting in hammering of the lesser digits and hallux valgus of the big toes (a veering of the great toe towards the lesser toes) which is a precursor mechanic to developing bunions. Furthermore, flip flops are made of a softer foam that compresses with use, wears out quickly, and they do not offer any integral support to the foot. While they may feel nice for a day or two or a week while on vacation, choosing them as a staple in your summer footwear rotation not only perpetuates existing issues, but can also cause new ones.

Flat feet

The flat foot needs support and control to maintain the neutral arch of the foot that flattened out during weight bearing. This excessive movement of the foot is a common cause of plantar fasciitis – the overstretching and aggravation of the plantar fascia, a supportive structure that runs the length of the foot, is meant to support, not over stretch, and this causes pain and discomfort. Treatment for plantar fasciitis and flat feet in general, is support and control. Most flip flops available are made of a flat foam material that does little to correct the excessive movement of a flexible flat foot type, and once the cushion wears out it’s not better than walking directly on the pavement.

High arches

High arched feet often cramp and have muscle pain from maintaining an unsupported shape throughout the day. Flip flops widen that gap and offer zero support for the higher arch to rest on. The flatbed of the flip flop does nothing to offload the heel and the ball of the foot (metatarsal heads) which takes all the pressure during weight bearing because of an unsupported arch. This can lead to increased development of calluses and corns, a thickening of the skin which can become painful in areas of high pressure.

When it’s time to make the switch

Flip flops may offer style for your feet, and are easy to slip in and out of quickly. However, if your feet hurt, it’s time to switch to something more supportive.
To sum up, you’ll probably want to reserve flip-flops for taking out the trash, showering at the gym, or wading at the beach. For anything more strenuous, opt for a more supportive sandal.
