The sole comes to the end of my heel just barely but most other size 9s I own have a bit more room (like at least a couple mm) so I feel like these run a tiny bit small. I purchased this shoe for my daughters wedding and love it! Took hours but finally mounted. on my new headset I used a peice of shrink wrap to put around the headphone jack to strengthen it. Me han encantado! I didnt want listeners getting lots of background noise, etc, when I was speaking. the company does send spares included in the purchase ( I am going to additionally add some heel covers that way I have no issues). So whilst I dont wear them out in public, if you too have a rather cold floor in your place I highly recommend giving these a go. Also you are without a mic for who knows how long. These sandals are comfortable & cute without looking like a childs shoe
