Have worked on my feet for 43+ years now. Began to get plantars fiiscitis in both feet about a year ago. Looked on-line at shoes that would take care of this problem and found NB978 were recommended by multiple reviewers. Took the advice to order 1/2 size larger and they fit great!  Been wearing daily since mid-January and cannot believe how they "cured" my plantars fiiscitis issues by the 2nd day. Have been worn in snow and rain and seem to be pretty waterproof. A great purchase for this satisfied NB978 buyer!
