And whereas these identical people will inform you they put on flip-flops for consolation, analysis suggests one of these footwear is commonly an enormous supply of discomfort.
And never simply that—it may well additionally trigger severe issues.

In a standard gait cycle, the motion begins with the foot making contact with the bottom on the surface fringe of the heel.
Because the forefoot involves the bottom within the stance section of the gait cycle, the foot begins to pronate, or flatten, to offer shock absorption. The foot adjusts to the floor on which you’re strolling.
The foot then turns into extra inflexible, serving as a lever for the muscle mass of the decrease leg as they contract. Because the foot leaves the bottom, it enters the swing section of the cycle.
If the second of pronation right here is just too pronounced or too drawn out, it may well have an effect on the complete decrease extremity.

The decreased operate with flip-flops contributes to extra power by the decrease extremity and decreased stride lengths throughout the gait cycle.
However right here’s the all-important query: What may all of this result in?
Properly, quite a lot of discomforts, imbalances and overuse accidents, a few of which embody plantar fasciitis, stress fractures, arch ache, bunions, shin splints, tendonitis within the tendon connecting your kneecap to your shinbone, knee and hip dysfunction or ache, bursitis of the knee and hip, low again ache and extra.
It’s not exhausting to see how flip-flops may cause some severe issues.
The excellent news? Summer season type and optimum foot consolation are nonetheless inside attain.
“When in search of a sandal, search for one with a contoured foot mattress with arch assist, versus flat-soled flip-flops,” stated John Harris, DPM, FACFAS, a Spectrum Well being Medical Group orthopedic foot and ankle surgeon. “As well as, decide a sandal that doesn’t require you to scrunch your toes to carry them on.
