My Isaac 2's
Isaac's were my favorites, but now they've succumbed to chasing the Hoka craze, which automatically makes Hoka better than these. The up-turned toe box and the extra thick soles now make climbing fire trails too slippy on dry dirt and sand. That's my experience, at least. They are extremely comfortable, but harder to use. I liked the way they were better. I prefer the Newton Fusion's now. Their lower to the ground and straight-toed.

Issacs 2
I have been running for decades in Issacs. When the original model, the Sir Issac, was discontinued I worried I may not find a comparable running shoe. Then the Issacs 2 appeared. I ordered a pair and to this day I continue to run in Issacs. Newton,s innovative technology and environmental responsibility are great. Just let me know in advance if the Issacs 2 will be discontinued so I can purchase additional pairs.

Newtons have been my shoe for 10+ years. I literally have 8 pair I rotate through right now. I train in them, I walk in them, I everyday in them, Ive even done a few Ironman in them. Ive been wanting to try these new Isaac's style for a while now as the OG Isaac where my first pair. And boy they havent disappointed. No foot fatigue, sturdy fit, look good. Id give 10 stars if I could.
