Review on Fupoia Slippers: Non-slip Moccasins for Boys' Comfort and Style by Joel Young

- It's 100% synthetic which makes me a little nervous. We've been trying to transition to using natural fibers in clothing ever since a study tested blood samples and found that chemicals in synthetic clothing can penetrate your skin and circulate. Another problem with synthetic fabrics is that they are not breathable, so they are warm and fluffy at first, but your feet can sweat in them, which in turn makes them cold. But the design and style are great. The size is accurate.
