Hi folks. Been lurking the net for my next go-to shoes. Can i have your opinions please regarding this matter? I'm currently rotating on Brooks Purecadence1 and Puredrift, being the former as my choice for long distances and half marathons. What i do like about the Purecadence is that it is very durable. I believe i am on my 400 miles+ and this shoes is not about to give up, not yet. In fact, i think i can get another 100 miles in them before ditching them out. Well, since i'm getting ready for their retirement, i'm on the look for a replacement and I'm eyeing the Kinvara 3. I have my doubts though on K3 regarding durability as i have read on different blogs/reviews about premature wearing, and like everyone does, i would like to get 400 miles + out of them. I'm 5'7" feet in height and weighs at 138 lbs, midfoot striker and spend most of my runs on road/pavements. My question is, is Kinvara 3 an upgrade? Sidegrade? Or downgrade from Brooks Purecadence? Or should i just consider buying the version 2 of Purecadence since the version 1 works well for me?
Thanks for any inputs you will share.
