So, if you're wondering which size Bare-X Lite 150 to order, go with the size you like for your f-lites or half a size smaller than the NB MT10. I wouldn't order a size smaller, though, because that would defeat the purpose of a wider shoe last. And, if I'd call the f-lites snug in this size, then the equivalent size 150 is downright roomy. I am wearing a US men's size 11.5 Bare-X Lite 150, because that's the size I like my f-lite 230s to be. The Bare-X Lite's toe curve is not so discriminating against my little toes. I've worn other shoes with wide toe boxes that have a peculiar slope to the front of the shoe, a curve that seems to exclude the existence of my littlest toes. Moreover, the contours of the Anatomic Last are nicely suited to my foot shape. This lack of floppiness is crucial to feeling fast, I've decided. It's a comfortably wide last without making the shoe feel floppy and sloppy on my feet. The Anatomic Last, a feature I was especially anxious to experience, is a real winner here. But, it's still very breathable, no worries about suffocating your foot, or anything. I'd say, though, that's it's not quite as open as the mesh upper of my Bare Grips or f-lites. The upper mesh material is comfy and stretchy like the other Inov-8 shoes I've reviewed. I imagine you'd like this feature if you were averse to seams in a shoe, someone who doesn't wear socks perhaps. Fortunately, that problem doesn't exist when the tongue is part of the upper like this. I'm often annoyed by shoe tongues because of the way they slip to the side or insist on creasing unnecessarily between your foot and the rest of the shoe. The absence of a true tongue is another special quality of the 150. (I suppose a picture of them on my feet might have been helpful) Just slip on the shoes, tighten, and secure the loose laces under the front-most lace to avoid looking stupid. Granted, I might be concerned about the durability of this laces-cinching contraption. (Push the little pushy thing forward to move the laces through the cincher) What do you call that thing, though? A cincher, maybe? Whatever it is, it's pretty efficient once you figure out how it works.

That's right, you don't have to tie them at all! Well, not the lacing, rather the manner in which the laces are tied.

Look closely at the upper in the photo and see that the lacing system is relatively unique. Synthetic Mesh, TPU Lacing Support, 3mm Footbed, Anatomic Last*
