  • A good number of purchasers were disappointed that the lace holders easily rip out of the shoe.

Bottom line

The X 17.1 FG boot is a great example of the “do not fix what is not broken” approach due to the subtle differences it has with its predecessor, the X 16.1. However, a lot of valuable things set this boot apart. Because of its one-piece construction, the touch on the ball and thickness across the entire upper is consistent. This is the very quality that most of the users admire about the shoe, on top of the minimal break-in time it requires. Many players were also in awe of its visually appealing design.

However, not all were fans of the firm ground cleat. There were users who were not satisfied with the strange internal sensation if offers and some of its durability issues. For footballers looking for good-looking boots that can withstand wear and tear, the X 17.1 is one sterling choice on the firm ground arena.

    Don't buy these with the expectation that they're gonna feel super super thin on your foot.

  • 91 / 100 by Eial • Eial • Level 1 expert

    Once you actually wear them, you'll notice that it's a little bit softer from straight out of the box.

Features of the Adidas X 17.1 Firm Ground

  • The Adidas X 17.1 Firm Ground features a TechFit compression upper that molds to the shape of the foot, giving it a second-skin fit. The heightened TechFit collar and the curved design at the back also offer flexible ankle support.
  • Furthermore, this soccer cleat uses the Non-Stop Grip (NSG) technology that enhances the grip on the ball.
  • The Adidas X 17.1 Firm Ground has the lightweight SprintFrame outsole as well. This TPU plastic material is flexible and moves nicely with the foot.

Fit and sizing

The Adidas X 17.1 Firm Ground is available in standard size and it fits true to size. The sizes are 6.5 to 13 for men’s version and sizes 5 to 10 for women’s version.


This football cleat uses the SprintFrame technology for the outsole. The forefoot area of this lightweight synthetic material is flexible enough to adapt to the movements of the foot. It also has ribs through the midfoot area to give it a bit of rigidity.

The stud pattern of the Adidas X 17.1 FG is the same as its predecessors in the X 16 series. It has six studs in the forefoot, one support stud in the middle, and four under the heel. It is a combination of hybrid conical-bladed studs and raindrop-shaped studs. The stud pattern is intended to increase traction and speed on dry, natural grass.


The Adidas X 17.1 FG uses the TechFit construction upper. This synthetic material follows the shape of the foot for a secure fit and excellent control of the ball.

The Non-Stop Grip on the upper gives it a thin checkerboard texture to keep the ball from slipping even in wet conditions.

The exposed lace of this football boot runs through five pairs of nylon loops that do not attach to the base of the shoe. The lacing system keeps the foot locked in place and prevents the middle part of the upper from stretching during changes of directions.

The Adidas X 17.1 FG also has a heightened TechFit collar. This stretchable sock system ensures that the ankle is stable and secured in place.

The curved design at the back of this football shoe alleviates tension from the Achilles tendon. The external heel counter that is connected to the outsole keeps the heel area intact.

Internally, this football boot has a soft, synthetic suede padding for added comfort.
