No, Bob. Your staff did not recommend it for bare feet, and I had no intention of diving with them in bare feet. However, after having to make a special trip to the UPS depot to pick them up last night, I was too thrilled with having them to take the time to get my booties out. I wanted to see them on me the moment I got them home.
I have tried them on with my tropical booties, my heavy wetsuit boots and my DUI drysuit boots. The fins fit great with all of them. The adjustment to switch between them is very simple and took almost no time. Pop two buckles and readjust the large velcro pad. Then connect the two buckles and tighten the straps. It went very easy. I was very impressed with the design. This afternoon, I will head down to the pool and give them a workout.
The bag is great too. I like the zippered inside pouch. Perhaps the next version of the bag you make could have a larger pocket inside that would be able to hold the comfort insteps when not in use. (I don't need it for the SD-1, but my wife thought of it for her Pros.)
