Somehow summer comes, and along with the warm weather a rite of passage seems to be the versatile flip flop. They come in all sizes and prices to meet every taste. However, they are not meant to be a shoe. The flip flop makers would love you to wear them daily as a shoe; but they do not afford the protection and support that a foot needs when walking.
Even the more expensive brand name flip flop do not have the padding required; the mere design affords little stability to the arches in the foot. In order to walk in them the toes grip at a point when the foot should be extending. However if we did that the flip flop would go flying as a weapon in the air.
The lack of support and the challenge in motor mechanics puts great stress on the bones in the feet often causing hair line fractures and strains. With the collapse of the medial arch the femur rotates and the bones in the leg have to reorient, sending referral pains up to knees and hips.
So the moral here is, just because they sell flipflops as summer gear, they really are only meant to be worn from building to ocean or pool. Short distances work well as appropriate terrain for flip flop wearing. They work well after athletic events; when one wants to remove the sport shoe and wear something light. They are however not not a substitute for shoes. Sandals often fall more in the same category, unless they have adequate padding and straps that keep them secured on the feet to allow for proper walking mechanics.
