    The X 17+ Purespeed is a continuation of the X 16+ Pure Chaos. The shoe follows all your movements and locks your foot in no matter what shape it has because the strap is free to move. The material on the toe box area is thinner and less airy compared to the X 16+. Out of the box, the shoe is very soft and it will break in almost immediately.

    The X 17+ Purespeed has a similar design with the X 16+ Pure Chaos, but with a slightly different texture. It’s a comfortable shoe out of the box. The heel lockdown is excellent.

  • 95 / 100 | Soccer Reviews For You

    The X 17+ Purespeed as a whole is a great top-end performer. On feet, it is very comfortable out of the box. The upper feels soft against your foot. The lacing system holds everything in place quite nicely. The heel liner does a really good job at gripping your heel, preventing any kind of slippage. The break in process is just a matter of getting used to the way the shoes feel.

  • 95 / 100 | Soccer Reviews For You

    The X 17+ Purespeed is an excellent shoe as far as performance is concerned. You get a barefoot feel when you touch the ball, although it has more bulk to it than Nike’s Mercurial line. The outsole has a Sprintframe construction featuring external heel counter that is one piece directly attached to the sole plate. This creates a very lightweight feel for the shoe. As far as the stud pattern is concerned, it is exclusive to the X line. The midfoot area is the tightest aspect of this shoe.

Features of the Adidas X 17+ Purespeed Firm Ground

  • The Adidas X 17+ Purespeed Firm Ground features a newly redesigned Techfit upper that hugs the foot comfortably. It provides the foot a more customized fit. This material offers improved lockdown and a truer touch on the ball for maximum performance on the pitch.
  • The football boot also features the Non-Stop-Grip (NSG) technology on its upper. It provides control in all weather conditions. It works in combination with the Purecut sock system that conceals the laces for that non-bulky feel over the area that touches the ball. The result is a superior feel and control of the ball that will help execute that powerful strike.
  • Another added feature of the X 17+ Purespeed Firm Ground is the X heel lining that grips the foot for that secure lock-in during changes in direction. Moreover, superb traction on firm ground is provided by the lightweight Sprintframe outsole, allowing players to move with speed.

Fit and sizing

The Adidas X 17+ Purespeed FG sizes are in the standard length for both men and women. This football boot fits true to size. Since it utilizes a knit mesh and TechFit technology on its upper, the X 17+ Purespeed delivers a soft and comfortable foot wrap.


The X 17+ Purespeed sports a Sprintframe outsole that is both light and flexible. This sole unit provides exquisite traction on the firm ground as well as on artificial turf. With a molded stud pattern that performs with a really good grip, this football boot delivers stable speed and a balanced footwork.

This version also features the "S" curve heel that was first seen in the extremely popular Ultra Boost. The curve works to relieve pressure on the Achilles tendon for added comfort in the heel area.


Lining the upper of the Adidas X 17+ Purespeed is a soft knitted material that hugs the foot comfortably. The upper also utilizes a Techfit compression technology that molds to the foot for an excellent ball feel and a comfortable glove-like fit.

The football boot adapts the Purecut sock system that is designed to cover the laces and give a clean, laceless look. More than just a visual feature, the lack of laces on the upper provides a bigger strike zone that can facilitate better, more powerful shots. The NSG micro texture on the upper is an added feature that guarantees superb ball control in any weather condition.
