No problems yet, but I am paranoid enough that I plan to baby these a bit. Heel height just right. Keep in mind, though, your pictures--taken through the plastic case--will be fairly clear but not perfectly clear. They are pretty good. We have had many Bose products over the years and we were very excited for this one to come out and actually pre-ordered it. Buyer beware, definitely dont wash them (or probably get them wet at all) - but they are pretty cool shoes! Last but not least - it makes me smile! I sweat like crazy just sitting at my desk working, by 10 am the waist band of my underwear and the back of my bra are soaked in sweat! I ended up buying a 3 foot USB extension cable in order to be able to use the lights. and this is where the film slightly falters, Craven goes back to his Scream/horror roots, and turns Rippner into an all slashing, all maniacal corridor stalker.
