Aging knees and a calf injury took me out of running some time ago, but I still walk, bike and hit the gym regularly. I find that cross trainers can be stiff and a bit tough on my feet so I went for some high end running shoes. Very glad I did. These had a perfect fit out of the box and my feet do not tire or get sore on walks and workouts that used to cause problems sometimes. I usually buy two pairs of shoes at once, and got a pair of somewhat cheaper Pumas at the same time. The difference is astounding, so I'm sending the Pumas back (fit problems also) and getting another pair of these. This great shoe is really worth the high price to me.
