Replied with potential solutions within 24 hours and followed up to ensure that all was well. I got these as an upgrade to the PX-100 But they just arnt as comfortable. I mean they are sandles so they can get away with being a little scruffy. Even my high tops were able to fit standing up! failed purchase, they are extremely slippery, run small All srews, nuts, bolts and pins were there.

My daughter bought this to try for her skin.
