I've had 3 pairs of this shoe over an entire year. I've used them for everything in my training. This shoe can almost do it all. It's so close to perfect. Let me explain. When you get this shoe out of the box, you can tell it's a very bouncy and energetic shoe. The foam feels great underfoot and it'll carry you through all your workouts and easy days and long runs. After 75 miles, I lost this bouncy feeling. I felt the foam compress more and not rebound as much. This feeling continues for the rest of the 400 mile lifespan. It's a good shoe for those long runs and easy runs but when you get to the harder faster workouts, this shoe loses it a bit. I feel like I have to put more effort into my stride and more force into the ground after the 75 mile mark. Also cornering in this shoe even on a track isn't the greatest. I feel unsure every time I take a turn because I feel my foot move in the foot bed
The outsole is also almost perfect. It's very durable and I haven't noticed any grip issues on trails and wet surfaces. I know this shoe is made for roads but you'll be fine on dirt trails and with running on gravel that isn't boulders. The only problem is the exposed midsole. If I could, I would submit a picture of my outsole. I'm at 304 miles on my current pair as of writing this review and the exposed midsole in the forefoot is COMPLETELY shredded. I'm not asking for complete rubber coverage but this is just insane.
Overall this shoe is an incredible shoe. It'll do whatever you want it to do. I've even raced a 5k in these. It will and can do everything well to very well. I highly recommend this shoe to anyone looking for a do it all shoe
