My son wore these booties all fall, winter, and spring.  They are soft, cozy, adorable, and they never fall off!  I often carry him in a front carrier with his little legs dangling out, and his feet would get cool unless he had these booties on. We got so many compliments on them. I ordered another size because we love them so much. Robeez may not be cheap, but they are so worth the money. You will not regret this purchase.
