I went ahead and bought a pair cos in all honesty I was impressed with the "upgrade". Took them out last night on a 9 mile jaunt, and I've gotta say that I've fallen in love with Asics all over again!! Right outta the box, they just felt PERFECT on my feet, and the more I ran in them the more impressed I was.<br>
Definitely an improvement in weight, slightly more comfortable toe box, and I think the heel fit just right (perhaps just a bit tighter than the 2110).<br><br>
I'm totally sold, and would love to at least see the trail version now.
