Changes

=Comparisons=

Here are some direct comparisons with its potential competition.

The Instinct 2 was softly cushioned, which made it a remarkably comfortable shoe, even though it wasn't up to the standard of shoes like the [[Asics Gel Hyper Speed]]. The main change for the Instinct 3 is the use of much firmer foam in the midsole. The Instinct 3 is a quite a bit lighter than the Instinct 2 (1.6oz), but that's not enough to compensate for the reduction in cushioning. The other noteworthy change is in sizing; a size 10 Instinct 2 is the same size as a size 10.5 Instinct 3.

The [[Asics Gel Hyper Speed]] provides more cushioning in the heel than the Instinct and similar cushioning in the forefoot, even though the Hyper Speed only weighs about two-thirds as much as the Instinct. This makes the Hyper Speed the clear winner, over the Instinct 3. (The Hyper Speed is far from uncomfortable, but when my feet are tired and beaten up, the softness of the Instinct 2 was welcome, but that's not the case with the Instinct 3.)

The [[Hoka Clifton]] is the best [[Maximalist]] shoe by far, combining massive cushioning with light weight. The Instinct is the same weight as the Clifton, but it offers far less cushioning. What the Instinct does offer is a shoe designed for the human foot, plus a little more padding in the upper. I would choose the Clifton every time over the Instinct, except those occasions where I didn't want to cut the toe box open. This would be in ultras where I'm walking a lot and having problems with debris getting in the openings. (That said, check out the Altra One below first.)

The [[Altra One]] offers slightly more cushioning while weighing quite a bit less than the Instinct. Both are remarkably comfortable and are shaped for the human foot. However the One will not offer the same level of protection from stones on rocky trails, and it can get stones trapped underneath. Also, while both are shaped for the human foot, the One has a toe box that doesn't quite have the height you need, so it may still cause toe blisters if you don't cut the toe box open.

The [[Saucony Kinvara]] 6, is lighter than the Instinct, has better cushioning, and is nearly zero-drop.

I like to compare shoes against my benchmark "normal running shoe", the [[Asics GT 2000]]. The GT 2000 is heavier than the Instinct, and has slightly more cushioning, but the two shoes could not be farther apart in their use of [[The Science of Running Shoes]]. The Instinct doesn't try to interfere with your stride, or encourage a heel strike like the GT 2000. Comparing how the two shoes feel, the Instinct is like running barefoot on a well cushioned track, while the GT 2000 is like running in a wooden clog. The Instinct is a clear demonstration of what's wrong with traditional running shoes and how they should be created.
