Not totally relevant, but I tried on the Nike Zoom Force 1 last year, and it was surprisingly comfortable and well made for a first year entry. I would expect no less from the Kaiju this year.
That NBx686 boot is really interesting. Too bad no local shop I know of carries it, so I can't try it on. I would never buy boots without trying them on first.
