PROS

  • Firm shoe with a fast ride;
  • Comfortable upper that hugs the foot well

CONS

  • Very rigid shoe which inhibits foot flexion and mobility;
  • high heel-to-toe offset which could encourage heel-striking

OUR VERDICT

The Adidas Crazy-Fast is a good lightweight option for neutral runners who enjoy a firm, responsive ride. The shoe is rigid enough for mild-to-moderate over-pronators, as your foot will stay securely in place with limited movement throughout the gait cycle.

Adidas Crazy-Fast Trainer General Information

The Adidas Crazy-Fast is the runner’s version of the famous Adidas “Crazy” basketball line.

This concerned me at first, as I prefer my running shoes not to be linked with alternative activities; running shoes should be specific to the sport, and my hesitation was that this model might be some form of advanced “cross-trainer”.

However, my first few runs in the shoe abated these doubts and confirmed that this shoe was indeed a functional trainer with a highly responsive underfoot ride.

Adidas Crazy-Fast Trainer Impression

The model I received was a striking black and gold, which was fine by me given where I live- Boone, NC is home to the Appalachian State University Mountaineers, whose banner colors happen to be black and gold… fitting, for sure.

Walking around my apartment, it was clear that this shoe meant business given how firm the outsole seemed to be. Firm outsoles usually feel best as your legs start to tire on longer runs, and I do enjoy a relatively rigid ride for longer outings or faster sessions.

The upper fit comfortably snug on my rather narrow foot, but was not restricting and I’ve suffered no blisters from the material. The laces seemed to be a little “ribbony”, and I have had to stop and re-tie them mid-run a few times over the last several weeks; just double-knot them securely or buy some lace-locks and this issue should be remedied.

My first few runs in the Adidas Crazy-Fast reminded me most closely of the Nike Air Zoom Miler (circa 2004-2005) and the Asics Speed Star line- both fast feeling, lightweight shoes with rigid outsoles.

I have completed runs between 5-10mls in the Crazy-Fast at variable speeds and terrains, but these shoes do feel more natural when running at faster paces on a paved surface. If you are a heel-striker, you will love how this shoe transitions you quickly towards the mid-foot during the landing phase of your gait.

If you are a mid-foot to forefoot striker like me, you may find this shoe to be a bit restrictive and a little awkward underfoot. It all comes down to personal preference.

Adidas Crazy-Fast Trainer Sole Unit

The outsole of the shoe employs Adidas’ “Sprint Frame” technology seen in several of their other models. As I have said many times in this review, this material is firm to hard, has limited flexibility, and a noticeable heel. It even struck me as being rather plastic-like in places, but this was not noticeable while running. If you are into more minimal shoes, you may prefer a softer and lower ride than this shoe will offer. However, if you are used to traditional trainers, this shoe will be a pleasant surprise that offers plenty of protection in a lightweight package.

I did notice my left heel being sore after every run in the Crazy-Fast, probably due to the high and firm heel platform on this shoe. I had plantar fasciitis for two years while in college, and it only recurs when I wear a certain type of trainer. Unfortunately, the Crazy-Fast fits that description for me on a personal level, and I prefer shoes lower to the ground with a softer ride to prevent the PF from returning.

However, I do not mean to imply that this model is faulty or may aggravate certain injuries, but I do caution those with a history of PF to consider this note.

Adidas Crazy-Fast Trainer Upper

The upper was my favorite aspect of the Crazy-Fast, designed with typical Adidas quality and attention to detail. There are no aggravating seams or liners to harm your foot, and the supple material used in the upper is wonderfully form-fitting.

After a few runs, the synthetic material conforms to your foot shape like a glove. I only completed one run in the rain thus far in the Crazy-Fast, and my feet stayed relatively dry despite the conditions.

Even when they were eventually soaked mid-way through my run in a downpour, I experienced no slipping, rubbing, or chafing which is always a sign of high-quality footwear.

Adidas Crazy-Fast Trainer Opinion

In conclusion, the Adidas Crazy-Fast is a good option for those seeking a fast road shoe with a flair for brighter color ways. While not a prime choice for mid to forefoot strikers, it does offer something for virtually everyone in terms of durability, comfort, and versatility on the road and track. Check them out at a retailer near you, and see if Adidas can help you run “Crazy Fast”!

We thank the nice people at Adidas for sending us a pair of Crazy-Fast Trainer to test. This did not influence the outcome of the review, written after running more than 50 miles in them.
