Shoe Review: Zoot Ultra Race 4.0

When Zoot first announced the new Ultra Race - I was a bit taken aback (and in a bad way).  Don't get me wrong - I absolutely love Zoot's shoe offerings.  They're the perfect shoe for me - mainly due to the "core" of features that they implement in their shoes.  These include the liner on the inside that allows the show to be comfortably worn at all distances without socks, the carbon that runs along the bottom of the sole that allows for a stronger toe-off, and a system (which varies between shoes but is available across their entire line) that allows to a quick on and off of the shoe.  Those are three EXTREMELY important things to me in a show and Zoot consistently has all of them.

So why was I disappointed with the initial announcement of the Ultra Race 4.0?  It was because the new Ultra Race had a unique lacing system that was a bit different than other triathlon/running shoes.  The new shoe model used the BOA system as a method of quick on and off tightening and advertised a "consistent and perfect fit each time the shoe is put on".

Wait a minute, why would someone be disappointed with that?  That doesn't sound bad at all - in fact, it sounds perfect!  Right?  Well yes, it does - but no, it doesn't.  You see, the BOA system and I go way back.    Way, way way back.  And way, way, way up.  As in - on top of a mountain.  The BOA system originated (at least my first exposure to it) in snowboard boots.  I remember when they first came out and were the hot item (and drove the price of some snowboard boots up to $500+!!!!).  I managed to score a pair and thought I was the coolest kid on the mountain.

Well, that all changed one day when I got off the ski lift and hopped down, slipped my foot into my bindings, cranked the BOA laces and - CRACK.  It popped off.  And it's in my hand now.  And my boot is no longer hugging my ankle - in fact, it's incredibly loose and floppy.  The trip down was - to say the least - slow and interesting.  I made it down without much of an incident and took it in for repair.  I got it repaired and the next day - CRACK.  Same thing happened, but to the other boot.  At this point, I gave up and just bought a normal pair of snowboard boots and forgot about the BOA system altogether (I actually avoided it like the plague).

That was the case, until I got these shoes from Zoot (all 10 or so years later).

The Ultra Race 4.0 is a lightweight (8.1 oz in my size 8.5) racing flat with a 10 mm drop (my measurement, could be slightly off).  They are an absolute true triathlon shoe that is designed to go any tri-distance.

So how did I like mine?

I loved them.  I'll get into the hows and why in a bit, but let's take a look at the shoe itself.

The first thing you'll notice is the colorway.  The shoe is not for the timid person who doesn't want to be seen.  These things are BRIGHT.  They look fast, they ARE fast - they make you look fast (whether you are or not).  I've gone on several runs in these and every single time someone compliments me (or at least makes a comment) about the shoes.

The features on the shoe are pretty standard fare for Zoot.  They have the same midsole which provides a firm ride without taking energy away from  your foot.  They have the strip of carbon that they put along the sole of the shoe to create a springy toe-off.  This seems somewhat of a gimmick at first (that's what I thought on my first pair with the carbon strip) - but it absolutely works.  When I run high miles (20+), my form begins to fall apart and I've found that the carbon strip helps keep the spring in my step.

Zoot's Carbon Span strip is in full effect on these shoes.
They also have an incredible upper (similar to the one on the original Ultra Kane) that allows for a compressed fit that still gives your foot room to move (and be free of socks).  
Zoot's Ultra Fit upper that allows for sockless wear and great comfort.

The big question for me wasn't about the shoe itself - but more about the lacing system.  Would the BOA lacing system be "up to snuff" and durable enough to handle racing?  The last thing in the world I would want it to come tumbling into T2 and have a malfunction in the lacing system on the run.  

The BOA system.

I'm happy to report that the system works great with these shoes.  A simple small tug on the BOA knob loosens the shoe (no need to turn to loosen the shoe) and a simply push tightens the shoe and a small twist (usually no more than a turn or two) tightens the shoe to a perfect fit.  If sized properly, the shoe should "fit" relatively well without even touching the BOA system.  The "lacing system" here is (as you can see in the picture above) put together of several strips of material that tighten around the foot as the BOA system is tightened.  This tightening, for me, was more of a "fine tuning" of the fit.  The shoe was pretty well fitted even before I messed with the Boa system and I feel I could run in it without tightening it at all.  However, when tightened, the fit only improved.

One issue that is (somewhat) common in Zoot shoes for some people is the "high, hard back" that is found on several of their shoe models.  Depending on the foot type and gait of some runners - some shoes with harder material that goes up higher along the heel/achilles can cause blisters that just don't go away.  I'm happy to report that this is not the case with the Ultra Race 4.0 - which has a "mid back" (for lack of a better term) similar to the one found on the Ultra TT.
The back doesn't go up too high on these shoes, which prevents blisters for runners with certain foot types/gaits (like myself).

I found that the shoe performed extremely well and held up to all my expectations when put to the test.  I've had it on a variety of runs from "race pace" 5ks all the way to 24 mile "long runs" and it has performed extremely well in all of them.  The water drainage slots (another Zoot feature in their shoes) worked extremely well.  I did a few swim/run brick workouts in the shoes and found that they dried quick enough to not become "sloshy" on the inside or encumber my run in any way.

These shoes are incredibly fast shoes and, while I have yet to race in them (that happens March 24th at the Fearless Triathlon Double Sprint), I'm confident I'll be posting some very quick run splits in these shoes.

All in all - this is a stellar shoe which absolutely outperforms other triathlon shoes in its class.  It's pricey ($180 MSRP) but is worth it in my opinion.  This is a lightweight, all distance racer that has a very wide range of feet that it would fit.  Not only do I recommend them, but my dog does to.


  1. Hi Bryan,

    I handle the public relations for Boa Technology, makers of the Boa Closure System, which is used on the Zoot Ultra Race 4.0 shoe you review here. We're happy you report having had a good experience with the Boa Closure System on the Zoot shoe. As you explain so well here, it is designed to "fine tune" the fit of this high-performance triathlon shoe.

    I'm sorry to hear, however, that you had a bad experience in the past with the Boa Closure System on a pair of snowboard boots; what brand were they? Did you know that all Boa-powered products, which now number for than 25 million worldwide, are backed by our "Dialed In for Life Guarantee" which provides free replacement parts for any Boa system?

    The warranty can be redeemed here:

    Plus, many of our top snowboard boots brands now employ Boa's most robust platform, the H3, which is our most powerful lacing system yet.

    Lastly, I would just like to point out that the Burton boot you picture here does not feature the Boa Closure System; rather, this is Burton's own lacing system.

    Feel free to contact me if you have any other questions about Boa or Boa-powered products.

    Wishing you all the best for the upcoming triathlon season,


    1. Elinor,

      No problem. The Burton shoe I linked to (somehow) had the picture change. Originally, it was linked to the "old" Burton shoes and now, somehow, it's linking to a completely different picture than what was originally on there. No idea how/why that it is.

      I've long since moved on from the Burton boots I had with the BOA system (and snowboarding in general) but I'm stoked to see that you guys have a great warranty!

      Like I said in the review - this system just flat out works for these shoes and I'm excited to see future offerings utilizing this lacing system.

  2. Bryan
    Thanks for your review.
    I have HORRIBLE HORRIBLE foot pain on the balls of my feet and started looking into yet another pair of running shoes. I've tried them ALL. I have BOA on my bike shoes and LOVE ADORE and CHERISH them! After Googling BOA and run shoes, I found the Zoots. After reading your review I think I'll have to give them a try!


    1. Gina,

      I think you'll like them. They're a great shoe. Pain in the balls of your feet could be related to a bunch of other things other than shoe choice, but I can attest that I haven't experienced any pain while running in these shoes. Best of luck with the Zoots! The female-specific color on these is pretty sweet, too!

  3. Bryan, would you say that these shoes are true to fit or did you find that you sized down a half size for the perfect fit? I wear a size 10 trainer, but don't want the 10 to be too large in the Zoot, having then to tighten unnecessarily.

    Any advice would be much appreciated! Thanks so much for the awesome review!


    1. I would say that they're true to size.

      I normally wear a size 9 and I have the 8.5 in these, but they're also very "race fit" fitting for me (i.e. TIGHT, which I like). If I were to get a pair to use specifically in longer distance races or everyday running - I'd probably go with a 9.

  4. Hi Bryan, great review. Do you do your long runs (20+ miles) sock less? Could one wear socks if they wanted to wearing the correct size shoe? I'm curious because I'm one of those triathletes that gets really bad blisters/cuts on toes or especially my rear Achilles if the shoe is high or rough on the inside.

  5. Finally a review of someone using this shoe! Would you recommend this as a running show, not for tri? Is the upper tight? I have a neuroma and anything tight is not good for me.

  6. Great review of this shoe. I have just acquired a pair of these and have a similar question about sizing. I normally wear a 9.5UK in Asics and found these, well snug and very tight to get on, certainly not quick. If I lift my big toe I can just feel on the join between sock and toe band. Sound about right or worth opting for the 10UK?

    1. I would size up - especially if you ever intend on wearing socks with them. They have a tight fit.
