The Slightest Deviations Matter

I went back to running without the insole in the Evo and it's a major
difference (hard to believe a 1/8 in. insole (2.5mm) has that much of
an impact)). I think I've pinpointed my threshold. Anything with
more than about 4mm of sole is problematic for me. I truly have to
run as close to barefoot as possible. My stride was quicker and I
landed softer without the insole (no choice when you are that close to
barefoot) and I felt more comfortable again.

There's a lot of trial and error in this running thing for each
individual but the great thing is when you start to really pinpoint
the thresholds that cause you issues. The last 3 months has helped me
more specifically define my personal requirements in footwear:

1. no more than 4mm of protection
2. no heel buildup
3. no arch support
4. no motion control
5. less than 8 oz. in weight (closer to 4 oz. is even better)
6. traditional toe box design (I like VFFs but not a big fan of the separate toe design)



  1. I was planning to buy VFFs but am having second thoughts. I think the toe design would annoy me also. I will try your no insole method.

  2. TokyoRacer, please let me know how it goes without the insole. I'm still struggling when it comes to fast paces on hard surfaces without the insole, especially downhill. It's not a pain/injury issue but the muscle activation occurs earlier with less protection on the feet which is great for injury prevention but not ideal for race pace goals.

    This is why I was considering the insole for racing and intervals on hard surfaces which is only about 25% of my running, otherwise there's no issue without the insole.

    I'm still trying to figure this out.
