adidas X, speed in boots
Our selection X brings together adidas shoes from the X range, dedicated to speed, including the Speedportal and Crazyfast models, in SG with screw-in studs, FG with moulded studs, and Turf with small studs for kids. Very lightweight and low-cut, they are suitable for wingers and full-backs who make a difference in their first few meters.
Acceleration, with studs.
The X range, from 2015 to 2024
adidas launched the X range in 2015, replacing the F50, with a promise: speed. For eight years, the line saw nine successive versions, culminating in the X Crazyfast, the last in the series. In 2024, adidas ended the X range and relaunched the F50 in its place. However, the X models remain in demand: their slim upper, rigid sole, and lightweight appeal to players looking for a light shoe for sprinting, especially wingers and rugby backs.

Speedportal and Crazyfast: two generations of speed
The X Speedportal, released in 2022, combines a lightweight Speedskin upper for direct contact, and a Speedframe sole with redesigned studs for acceleration in all directions; it weighs around one hundred eighty-nine grams. The X Crazyfast, which follows in 2023, gains a few grams thanks to its Aeropacity Speedskin upper, a reinforced single-layer mesh with a transparent film placed in support areas. Both models fit snugly, like a second skin.
SG, FG or Turf: which X for which surface
In rugby, the SG version with screw-in studs is the most useful: it maintains grip on wet grass, where a winger starting out cannot afford to slip. The FG version, with moulded studs, is suitable for dry pitches in September and late year. The Turf version for kids, with small rubber studs, is used on stabilised surfaces and hard synthetic pitches at rugby schools. In all cases, the X offers little protection for the foot during contact: it is made for running, not for pushing in a scrum.

Frequently Asked Questions
Does the X range still exist at adidas?
adidas stopped the X range in 2024 and replaced it with the F50, which serves the same speed purpose. The current Speedportal and Crazyfast models are thus the last representatives of this line.
X or Predator: what's the difference?
The X is designed for speed, with a slim upper and lightweight sole. The Predator focuses on control and striking thanks to its rubber wings: a winger leans towards the X, a kicker towards the Predator.
Is an X SG allowed in rugby?
Yes, as long as its studs comply with World Rugby regulations: a maximum of twenty-one millimetres, rounded edges, no roughness. The referee can check the shoes before the match, so it's wise to regularly check the condition of the studs.
Is the X suitable for a child starting out?
The Turf model, with small studs, is suitable for kids training on stabilised or hard synthetic surfaces. On wet grass, it has less grip: for weekend matches, a sole with moulded studs is safer.
Does the X Crazyfast fit small?
It fits very snugly and its shape is narrow. A slim foot keeps its usual size; a wide foot may feel tight at the front and should try it on with match socks before confirming its size.
