When you practice yoga, your body can experience many changes from your head to your toes. Your muscles strengthen and become more defined, you become more flexible, and your posture improves so you may appear taller. What about your feet though?
I've heard of people's shoe sizes changing after practicing yoga for a while. The reason this may happen is because your feet are so active when doing yoga poses. You're always working on spreading and relaxing your toes, and pressing into the little toe-side of your foot to help lift your arches. It's like a strength training workout for your tootsies, making the muscles in them stronger. This happens with dancers and gymnasts, too, and many will experience a slight increase in shoe size. This isn't a bad thing, it just means that you are working your feet, which will help improve balance and prevent injury.
Yoga may also result in a decrease in shoe size. To find out why
If you're practicing yoga and losing weight, your feet may shrink a little. It's not necessarily because of yoga, but just the fact that you're dropping pounds. I know you'd much rather lose weight elsewhere, but since you can't choose where the fat melts away, you'll notice you lose it overall. Tell me, have any of you encountered a change in your shoe size?
