I didnt know how much having a flat cord makes a difference. I can even just go into my home office at night after my wife is asleep and they?ll switch right over to my desktop Mac?s Bluetooth and I can listen to my music without waking her. The 518 is like 10 years old and I used it for like 6. Originally bought a size 4 because I was advised to go smaller but they ended up being too small so I got a refund and they were quick and efficient and so my mum ordered them again but in a size 5 and there perfectReally good safe buyerGood quality gents shoes take a square each but ladies shoes usually can fit in a pair per square Great choice of colours BTW, but it?s rare for online suppliers to have every colour in stock in every size. They ping all the buttons for what a good sandal should be. I hate wearing footies with work shoes but I may have to start if I can find anything low enough that would stay on with the he heel likely wanting to push the sock down since they are rubber. 5 - 10 and both those sizes were in that range. I got a large since I?m 5 months postpartum.
