    The X 18+ feels really good. From a comfort stand point, there really is nothing to complain about. For the most part, they feel pretty much just like the X 18.1 even though it's not a Speedmesh upper.It's what they're calling Skeletal weave. It's soft. It's flexible. It does have that second skin sensation.

Features of the Adidas X 18+ Firm Ground

  • The Adidas X 18+ Firm Ground is definitely not just your ordinary speed boot. This flagship from Adidas does not only wow with a bright and bold silhouette, but it is also packed with the brand’s top innovations that truly make it one stand-out boot on the pitch. Compared to its predecessor, the Adidas X 17+ Purespeed Firm Ground, this new generation football boot has underwent a major redesign.
  • Crafted to perform with a highly-responsive touch, this football boot is lined with a Skeletalweave upper, which consists of an ultra-thin grid of woven yarns. This lightweight upper provides a direct touch as well as a form-fitting wrap around the foot, resulting in a second-skin feel.
  • This Adidas cleat also highlights a low top Clawcollar. Engineered to somehow resemble a claw, this collar works to fasten the foot into the shoe for supreme stability. Moreover, this firm lock-in, alongside the upper’s skin-tight fit, eliminates the need for laces. Hence, its sleek laceless design.
  • Another feature of this football boot is its Standout 3D molded heel that reinforces a secure fit. This detail also provides cushioned zones that allow optimal movement of the ankles.
  • On its base, the firm ground version of the X 18+ sports an Ultralight Speedframe outsole. This lightweight sole utilizes a perforated design that facilitates acceleration. Moreover, firm ground stability owes to the boot’s stud configuration that combines Arrowhead forefoot studs with round heel studs. This setup enables players to make smooth shifts in movement on the pitch.

Fit and sizing
