These boots are great. Arrived earlier than expected and at a decent price. All By us stores are sold out for just $120 a pair! My son is 9 and wears 6 1/2-7 sneakers. So he still wears children's shoes, but boots are limited to size 6. I ended up ordering a size 7 1/2 and he has room to grow. About the Thumbs The length of the nails is worth the space, so they should definitely help us get through the Fall/Spring season!
