Just a casual runner, so take it for what it’s worth - the Rebel v4 doesn’t feel cushioned enough for me. I wasn’t getting any pain but coming from running on the Invincible 3s and Nimbus 25s, the Rebel 4s felt very flat. I’m not an experienced runner, and have run in the invincible 2s/3s, Propel v2, Nimbus 25, Rebel v3, Endorphin speed 3.
I love the look of the shoe, the fit is much wider than the v3 (which is a big positive for me), and the shoe felt very stable and responsive. However it lacked the “bounce” for me of the invincible 3s and lacked the plushness of the Nimbus 25s. For reference, I’m a 39, 6’1, 190lbs. I’ll continue to run in them and see if they’ll grow on me, but I’ll likely stick to the invincible 3s in the future.
