Ugg boots are incredibly popular.  Those squishy suede boots lined with soft, nubby sheepskin. But if you wear them on a regular basis, the comfy boots can put your body in a world of hurt.

Uggs were designed to warm the feet of surfers after a long day in the ocean. And despite the fact that they weren’t designed for long-distance walking, they’re so comfy-cozy, that diehard fans rarely take them off. And that’s not a good idea.

After wearing Uggs from dawn to dusk for about a month, you could get tendinitis. Podiatrist Dr. Krista Archer says, Uggs have no arch support so with every step, your ankles roll inward, and your arches and tendons collapse outward. And regularly walking in them can cause pain in your feet and ankles, and throw your walk out of whack causing problems in your knees, hips and back.

There’s even a name for the irritating, foot-dragging sound people make while walking: the “UGG shuffle.” And because the boots are often worn without socks – and feet sweat a lot in fur - the lining breeds foot fungus. So wear them as they were intended, as slippers to warm up your feet after a cold day, not as your go-to daily footwear.
