I have owned many Rockport shoes over the years, but these are the first from the Prowalker line I have purchased. I bought them from Amazon's sister company, Zappos.  Normally, I wear size 14 but the Prowalkers in 14 were definitely too small, so I ended up with size 15 and those fit fine.

I did quite a bit of walking (and driving) in the Prowalkers and they never gave me a problem - comfortable and no irritation from rubbing.  The appearance is a bit dressier than most walking shoes, which is exactly what I wanted as I wore them to customer meetings and will wear them on a European vacation later this year.

Clearly it is too soon to know about reliability, but I will be sure to update this review should my opinions change.
