/*UGG*/-style boots are as popular as ever, but new evidence questions their potential long-term health effects.
The Australian-made boots typically are suede on the outside, and sheepskin on the inside. They're popular among celebrities, and some people love them so much, they wear them all day long.
Podiatrists warn, they don't provide good arch support.
"What that leads to is overuse, meaning the muscles, the tendons, the ligaments, and the bones in the foot and the ankle over work. A recent study just came out that showed the correlation between a flat arch, and problems with the knee, the hip, and the back," said podiatrist Rick Positano.
The same goes for flip-flops.
Podiatrists tell patients they're okay to wear in social situations, but wear shoes with more support for things like long walks, hikes, or other recreational activities.
You can also add foot inserts to your Uggs, to add arch support.
