I found the Adios 2 to be really pointy up front, squeezed my toes together. Wonder if that had something to do with it? Not sure if the Boost version is roomier or if sizing up did the trick, but I like these a lot better.

Yes, same size as all my shoes. I can understand not liking the toebox, though. I think shape is the most important thing in a shoe. It doesn’t bother me. I did have to mess with the laces a lot (on both the Adios and Boston) to get them right. I typically wear laces very loose or I get top of foot pain. Thanks for your reviews. Looking forward to your Kinvara 3 review ;o)

Interesting point about maintaining form, I’ve just finished reading Dhar’s book also and he makes some interesting observations about form. I find it fascinating that coaches in Kenya seem to spend little time worrying what their athletes are running in… Because they all have fantastic form from running barefoot as kids! It seems that a shoe can’t teach great form!

On the adios 2 I was at the london marathon a couple weeks back and as a shoe enthusiast was looking out for runners in adios as it’s my shoe of choice. Outside of Kipsang and maybe a couple of other Adidas sponsored runners there were a load of guys (both elite and Mr 3-4 hours) running in the first version of the shoe. I have both but haven’t yet put miles in the 2, however it seems that the general feeling was that the adios 1 was a super popular shoe and the update hasn’t offered anything new. In fact the reason the 1 is still sort after may be because it’s a little less fussy in the upper and gives a bit more flexibility as a result? Either way it’s a racing flat with a safety net and a great shoe!

FYI, I snip into the shoes at the shoelace trim/frame and don’t lace the bottom 2 holes for a comfier fit.

Edit: Just realized another change they made that ties in with your tight toebox remark, the previous version has less trim at the toes so more room for feet to splay, now it’s like a peephole so more constrained. Grrr.

I agree about the better feel at faster pace. I actually think I would use these more often if they just opened up the toebox a bit – scrunched toes drive me crazy. Wonder if sizing up would make a big difference – do you wear your standard size in them?

That’s exactly what Finn is saying – they learn good biomechanics in childhood so the shoes don’t matter so much.
