Very pleased, just plug and play. My daughter is a true 12 and these were a big snuggle on her feet. These shoes are worth the price tag and after looking around a bit, I did find Amazon prices to be the most reasonable. Theyre slightly different but in practice I got used to both equally. I would recommend trying a different product. 5 (US) in den Schuhen, das passt in der Regel. The only gripe that I have is that for the mechanically challenged - assembly will frustrate you. These speakers are awesome! I needed a pair of good shoes to use for cave tubing event. Im 52 and 115lbs and found it didnt achieve the little lift I was looking for at all.
