They follow up with you for any questions or issues and replies fast. 0 lb each. My ten year old has severe adhd and has the hardest time focusing. The next time I wear them, I plan to toss them in the dryer and put them on my feet while still warm. The bottom shoe would either stich out or you risk getting it squashed. One thing to note- the back and sides of the bodice are not lined, and neither is the band around the waist. Purchased this case for my Beats Headphones. Hope some of this helps. The tight grip feel when holding it in the hand is nice + the bulkiness is actually not bad at all. Huge save in money and they?re super sturdy, not like a regular slipper.
