I am usually a size 10 and have wide feet. Buy these straps! After reading reviews that described the pillows as ?lofty? and soft, I decided to go for it. As always, everything stays put and is well supported by these briefs. Have only worn indoors so far. I am not sure if there is any difference between the two, but I found that the old (blue) ones would last longer. Very chic, very well made and comes in great packaging! Die Soundqualität leidet zwar ein bisschen aber verkraftbar. I would LOVE to give this product five stars, but we?ve had them for less than 3 months as indoor shoes only and one of them has stopped lighting up completely. The volume is very low.
