Saucony S10551-35: Women's Kinvara 11 Blackout Running Shoe (9.5 B(M) US Women)

This is my first pair of Kinvaras and I am elated with them. Compared to my other shoes, they are lightweight but have plenty of cushioning. And they are fast!. Each week for the past 8 weeks I have been doing interval workouts on a track in my old shoes, trying to improve my mile time. My beginning time was 8:21. After 8 weeks of intervals, I timed the mile again (in my old shoes) and got 8:01. Then, one week later, my Kinvaras arrived and I took them out on the track and ran a fast mile. I wasn't even pushing as hard as I had the week before since the mile was supposed to be one of the intervals... I ran 7:50! I feel like I'm flying. My calves and ankles and feet get more of a workout in the Kinvaras so they were tired for a couple of weeks. I'm guessing this is because of the lower heel drop. My legs have adjusted without injury or undue stress. Thanks for these shoes. I really like 'em!
