I might look at moving the motion sensor around at some point - it still works but its sometime a hit & miss. Its a little uncomfortable because the pressure on the temple is a bit much but not real bad. i went three sizes up yet the size was little uncomfortable. Nelle orecchie stanno abbastanza saldi ma sembra di avere infilati 2 tronchi dalbero. However I think the hype for the product has maybe outgrown the reality. They have drainage on the bottom that provides a way for sand to escape and keeps them comfortable. Very comfy, Just the sole isnt skid proof? and a little thin. After much searching for price vs. These are my second pair. This really is a versatile shoe to bring on any vacation.
