He didn't want me to wear the MBT's because I have the kind with the open back (alas, that's the only kind of shoe I like to wear... virtually all of my shoes are sandals and slingbacks \:\( )He didn't say anything about the rounded sole. The sole is very similar to the sole of the walking boot. I've had them for a couple of years and they're great for walking.

Hope you're okay. xoxoxo
