If in between sizes I would recommend getting the bigger size. All in all, you cannot beat this product for the price. The wedge is the same as a patricia, but the top of the sandal is different and fits me even better. I like that they come in multiple lengths so you can coordinate them in tight spots. Great rotation. Also fantastic for group conference calls as the built in 360 degree microphone picks up all voices no-matter which side of the microphone they sit. Great sound, great price but tangles like crazy. For example, for the top bar, you can do different variations of pullups. smart watch holder does not hold watch well. It?s really nice to have at work because the track pad is difficult to maneuver
