9 reasons to buy

  • Most of the users say that CrazyLight Boost 2.5 is truly a lightweight shoe.
  • Because of the perforations in the toe box, many remark that the ventilation provided by these low-top hoop shoes is A+.
  • One reviewer loves how the shoe is higher on the heel and lower on the forefoot, saying that it keeps him on his toes but also allows him to rest his heel on the soft Boost cushion.
  • A great number of reviewers express that they find the shoe beautiful.
  • Some users say that the traction on the CLB 2.5 gets the job done. The outsole does not rack up on dust that fast.
  • One tester says that once you go half a size down, the fit is quite excellent.
  • Because of the external heel counter, several users notice that the support at the heel is very comfortable.
  • Some feel that the Primeknit and mesh upper is quite sturdy. The third James Harden basketball shoe from Adidas provides nearly the same sturdiness.
  • A few buyers say that the shoe’s price is a great deal.

7 reasons not to buy

  • A few testers say that for the traction to reach its full potential, the shoe needs to be broken in. The HOVR Havoc basketball shoes from Under Armour require quite the same amount of break-in time.
  • Many users advise not to use the Adidas CrazyLight Boost 2.5 Low outdoors since the traction pattern will wear off fast due to the shallow grooves.
  • Almost all of the buyers mention that the shoe runs large, especially in the forefoot area.
  • Some testers did not like the adiPRENE+ cushioning in the forefoot; saying that they needed to insert PU insoles to make the forefoot feel comfortable.
  • A few testers mention that the shoe’s support is weak and causes some foot slippage.
  • Some say that while Boost compresses excellently; it still leaves some extra space within the shoe when it sinks due to pressure from the foot, especially the heel.  
  • Because the CLB 2.5 Low features an asymmetrical tongue, a number of people find the fit awkward; and it takes them some time to get used to the fit.

Bottom line

Overall, the Adidas CrazyLight Boost 2.5 receives mixed reviews. Majority of the wearers love the shoe and say it’s amazing, while expert reviewers are not so thrilled about the shoe’s fit and the polarizing feel of the cushion. High-flyers and players who like transitions from heel to toe, however, will love these Adidas low-top basketball shoes because of its excellent impact protection and responsiveness on the heel.

Good to know

Adidas gives another lightweight option with the CrazyLight Boost 2.5 Low. The Primeknit upper and Boost heel cushioning stand out as the main features of this shoe–providing a comfortable snug fit and great cushioning.

Cushion. The CLB 2.5 Low has Boost in the heel area and adiPRENE+ cushioning for the forefoot. The Boost cushion helps energize each step and protects the foot from impact. The shoe also features the new Adidas Stableframe technology. This basically means that the midsole is angled, wherein the heel is slightly higher than the forefoot, keeping the wearer on their toes–ready for the next move.

Traction. The shoe uses a blade-shaped herringbone pattern with micro blades on the outermost regions of the outsole. Because the outsole is made of soft and pliable rubber, it is not recommended for outdoor use.

Length and Width. The CrazyLight Boost 2.5 is said to run large, so be sure to go half to a full size lower.

Lockdown. The shoe features a wrap-like asymmetrical tongue design that locks the foot down onto the medial side. The Primeknit upper conforms to the shape of the foot and holds it in place while an external heel counter ensures that the foot is secure from the base.

The shoe uses a one-piece Primeknit cleatie construction that stops at the medial side to form the shoe’s tongue. The toe box area has fuse overlays to protect the shoe from toe drags. The upper provides a comfortable sock-like fit that’s breathable and feels very lightweight.

Boost and adiPRENE+ cushioning are used in the midsole while the midfoot features Adidas’s Torsion system that gives support to the arch. A non-marking rubber is used on the outsole.

The Adidas CrazyLight Boost 2.5 Low matches form with function.  Its low-top cut affords the wearer a wider range of motion. its Primeknit upper gives it a touch of luxury.

An aesthetic material overlay runs across the shoe,  covering the area where the mesh and knit are joined together. Styling varies for each colorway, depending on the materials used.

The Adidas Equipment logo can be found on the external heel cup and the tongue. Most of the colorways feature subtle Three Stripes on the forefoot.
