Shoes are a perfect fit. The talkthrough feature on the PXC 550 is missing as far as Im aware from the QC 35. The straps around the toe are comfortable . Didnt want to spend a lot of money so I found these. The idea of really basing our food consumption according to the seasons and what is available is old and hardly ever noticed anymore. Also, the IGI report # could not be verified. One suggestion to the manufacturer would be to put a small shelf at the bottom for extra security from slipping down. If i wasnt all the way in Jamaica i would return it but lets see how it holds up under my 8 year old light weight This stand will be a snap to take to cross races for repairs and cleanup. I wish I had found and bought this years ago.
