![]() There is clearly more arch support at mid foot now from this sockliner and the addition of 5mm of platform width. The glued in sockliner changes from a flat type to a more contoured one at the arch. Incredibly consistent to tie and once tied over the foot feel lacing approach here, and front to back. The lacing system is very easy to adjust, no struggles to move the laces through the webbing loops and once laced up never any adjustments for me. The system allows the laces to wrap securely over the integral knit tongue with tension through the webbing straps and strip providing the lockdown. So, except at the last lace up hole, no laces touch the foot as one would see in the usual in and out of holes approach as found in v1. The lacing system features a pliable external plastic strip through which webbing lace loops run. Once the foot is seated with a resounding thud, the rear of the shoe is totally locked down and on the run is very stable and secure, and for me more so than any other super shoe to date. It is not easy to pull on as the knit tongue and opening has minimal stretch, a great sign for such a minimal thickness upper and for rear lockdown. It also differs from v1 in having a far higher, more stout, and more padded heel collar. It differs significantly from v1’s and any other upper I can recall in being able to “stand on its own '' By that I mean it has enough inherent structure to the material to not collapse anywhere when off the foot yet on the foot it wraps securely, completely, and with no pressures.Ĭontributing to an all of a piece fit is that the knit, unlike v1’s, is in a seemingly random pattern with more depth or 3D structure whereas the v1 is more linear and flat and a bit softer It is completely unlined, highly breathable and low moisture absorbing.
