I did wear them into the water at the beach one day and it seemed like some water got into them. Easy to assemble, nice looking for the casual wine drinker. Another big problem is that this Birkenstock London is made in Portugal (which is omitted in amazons description so you assume all is made in Germany) while the footbed insert (which is not removable) is made in Germany and therefore the fit is off/different. I still have Mephisto shoes and sandals that I purchased 6 years ago and they look as good as when I first bought them! much more comfortable if you need to adjust them. I have always loved music and headphones and have been through many low to mid priced over ear headphones. This unfortunately doubles the amount of slack causing an undesirable amount of movement of the bike racks. I should also note that there was a light "white noise" when nothing was playing (the AirPods Pro and Sonys also have active ANC, but no such white noise), but this did not bother me too much (your milage may vary). Very cute and good quality, but the front cuts into my foot. I sit and work behind a computer all day and I wear these at my desk.
