Having completed the first Avon Breast Cancer 3-Day walk (1998), I know all too well how grueling the training and walk itself can be. I am therefore always pleased when I can recommend a shoe which withstands the demands and rigors this event requires. New Balance 1123 is a running shoe which provides maximum support, stability and it even has pink trim!
This shoe is a tank and it works for wide and deep feet. It also has mesh on the inside which works if you have a bunion. It has medial and lateral midsole EVA and no hourglass in the waist which especially helps if you pronate. Bottom line, this is a really terrific shoe but pricey, so make sure you use your 3-Day discount card when purchasing.
