I started my affair with the All Out Peak which lacked durability in the upper sides. The Agility Peak 2 has great durability and more breath-ability in the uppers than the Agility Peak 3. The Agility Peak 3 is a better Cold Winter shoe. However I have had to replace the lacing system in both the peak 2 and the peak 3. The original All Out Peak has much better lacing system than this latest incarnation of loopy loops. As you see in the picture I've cut out the loopy loops and replaced the cheap stretchy laces with half round laces 110 cm. The Peak 3 require 120 cm laces. The peak 2 has a wider out sole and maybe better stability. The cushioning is great in both shoes ideal for longer all day trail mountain running. I remain a fan. Just wish Merrell will pay better attention to the lace system. But hey I got em cheap on Amazon. Can't complain about that.These shoes are very light-weight and very comfortable. Although they fit my feet like a glove, they have plenty of room in the toe box, and the are snug at the heel (a good thing). I've only had these (and another pair) for a short while, so I can't comment on their durability. I enjoy wearing them on long walks in the city and country side. And I wear them to the office on occasion. Great fit, comfortable, and very light-weight.It looks good, feels good on foot. Great grip on road. I don't like the laces, too small.Quality fit and construction. Lightweight and non-skid. The pair I bought had the longer shoelaces company must of corrected issue. I’d buy these again for sure. My husband usually buys Brooke’s but these were a good buy and I’ve had the Merrill brand before with much satisfaction.I love Merrell shoes and decided to try out some of their sneakers. I've spent the day on my feet in these sneakers and never caused any issues comfortwise. I would definitely buy these againWhat a great shoe! Sleek, stylish. Fits exactly the same as my other Merrell shoes and hiking boots, same size worked.I have several pairs of Merrill’s & love them all.I just really like how it feels
