The X-Wave Air is made mostly from suede leather and mesh panels—specifically, “abrasion-resistant” mesh, says TCX (we certainly hope so!). It’s a lace-up shoe, no handy zipper along the side like some of TCX’s offerings, but getting in and out isn’t as bad as some other lace-closure boots I’ve tried. I was surprised at how rigid the rubber sole is, considering the X-Wave Air is pretty casual. It’s comfortable to walk in, but there’s no way a footpeg is going to poke your foot through the sole if you stand up or take an impact (again, the same can’t be said for some other boots and riding shoes). The last note I have on construction and general fit is that the X-Wave Air runs large. My pair is a US size 9, or Euro 43, and it’s a little big on me even though I typically wear a 10.5 or 44.
