At one time I was a serious runner. You name the shoe and I wore it at one time.  Now I'm a serious brisk walker. Same icy, muddy, gravel and dirt routes that I used to run put at an aerobic walking pace. These shoes soles grab the ice, the mud and perform wonderfully. They don't last as long as I wish they would last.... But I do put in 26 miles a week. So thinking about the health of your feet, knees etc... You may need to buy 2 pairs a year. Find them on sale and get out for that so important moderate exercise at least 6 days a week.  The shoes might be expensive but is not your health worth it?
