I am 60 years old and walk/jog 3 miles per day.  I ordered the orange (vizipro/citron/blue) Progrid Guide 5s about a month ago and liked them so much I ordered the blue (royal/citron) ones and they were delivered by UPS today.

These shoes are lightweight and quite comfortable for walking or jogging on any type of terrain.  The flat laces are just the right length and they stay tied for as long as I have the shoes on, unlike some others that come loose after an hour or so.

In the past, I have always worn one pair of shoes all day and when walking/jogging and did so until the soles started wearing out.  Then I got another pair. Now, I have 4 pair of Sauconys and one pair of Hi-Tec waterproof hiking shoes.  I wear each pair for one day and then switch to the next pair.  This keeps the shoes in like-new condition for quite awhile and my feet feel much better.  For over 40 years I had a large callous on my right foot and rough edges on both my big toes.  Since I have been switching shoes each day, the callous is rapidly disappearing and the rough edges on the big toes are gone.  My feet are actually smooth again and I credit it to wearing a different pair of shoes each day.

I highly recommend these Saucony Progrid Guide 5 running shoes. They cost a little more than a lot of other brands, but I really think they are worth it.
