I love this shoe. I have had it on for 2 runs now each about 8k (5 miles) and they are so soft and cushy but as expected with a toning shoe my thigh muscles feel the burn. No shin splints or ankle issues. I've had an ASICS and NIKE running shoe but this one takes the cake so far. One word of caution - mind where you're running, I happened to trip over an uneven running area and it was not easy to regain my balance as it would have been in an ordinary shoe, I literally almost fell on my face. Other than that, get these shoes! They are so worth the price.
