The upper mesh Nike Air Max Thea UK Outlet is open in the midfoot and forefoot to provide for some air flow. Unlike the new Free 3.0 Flyknit, which I have heard fits fairly tightly, the 4.0 has a traditional tongue, and I think this allows for better customization of fit. I¡¯ve run sockless in the shoes a few times and have had a bit of abrasion on one run near the midfoot/arch (maybe from one of the Flywire bands?), but this has been inconsistent. May have just been a hot day with more sweat leading to chafe. No issues at all while wearing socks (side note ¨C these shoes seem to hold a stink when you use the Nike Free Run 2 Mens Cheap UK m sockless).

I¡¯ve honestly found it really hard to not pull these shoes out for most of my recent runs (though the Saucony Kinvara 5 is giving them a run for the money as current favorites). I¡¯ve run just over 40 miles in them so far, with a max long run of 14 miles. I¡¯ve run from easy pace down to 5K pace. They¡¯ve worked well for just about everything. I¡¯d have no hesitation in taking them beyond 14 miles in a single run, I might even consider them for a marathon. They are a bit too flexible for my taste for speed or a 5K, and the sole grooves would probably collect too much debris for off-road use, but they are versatile enough to handle jus t about anything else I could throw at them.

I¡¯m really hard-pressed to come up with anything negative about this shoe ¨C I think the only issue I¡¯ve had was with the fact that the size tag is stitched to the underside of the insole and I can feel the stitching under my heel. It wasn¡¯t bad with socks, but it was noticeable when I went barefoot in them. It might be possible to cut the tag and remove the stitching, but I was lazy and just swapped the insoles out fo Nike Free Run 3 Mens Sale UK r an identical one from an older pair of Free 5.0s.
