I found the Maono support team to be helpful, always courteous and very responsive to every question I had. My daughter just wears her old 4s even though they are a little small because the new 5 is too big -- weve set the sz 5 aside for future wear. Have 4 different colors now, very comfortable shoes! However, they do not fit to size. I can walk around in them with socks on also with total comfort. Just one point of caution in that vehicles or traffic arent filtered out by the noise cancelling functionality, which is my only real gripe. Sturdy materials. I did not care for them cold, but they are very acceptable and taste like hot chocolate if you warm them up. Very comfortable, didn?t need to break in to wear all day. The minor characters are highly entertaining and add a welcome touch of quirky comedy.
