Light on the feet..and I have no joint pain what so ever when I am finished my running!!  I usually with most shoes experience hip, back, neck, and knee pain (I have broken my back twice so pain free and less impact is important to me) and these shoes give that to me..pain free running!  I actually bought some from REI in the blue/green color and loved them so much I found them cheaper and in a different fun color on Amazon..so I bought them, and now own 2 pair!  Mizuno's are the best!
