I took the new Brooks T5’s ($90 @ LRS) out for a 4-mile tempo run run yesterday, though I’d share some info for those in the market for racing flats.
First, the looks:
You either like the design or you don’t. I’m pretty neutral here, but I think it’s a great improvement over the T4 model. I believe the color scheme was the only real change from the previous model, so if you liked the T4, nothing but good news.
Size:
I wear a 9.5 in every brand and style running shoe I’ve used, but I required a size 10 in the T5’s for a comfortable-yet-snug fit. More on that later.
Feel:
Being a minimalist racing flat (6.7oz.), it’s surprisingly substantial under foot. I’m 180lbs, midfoot striker, and normally run in performance trainers (Tangent 2, Mizuno Elixer) or Mizuno Riders. I was expecting much less impact protection, and to be honest, expected some discomfort to start up somewhere in the 3rd mile. Never happened. At the end of 4 miles, I felt comfortable that these could easily go 10K and up to a half-marathon for a guy my size, possibly longer. If I was 150 or less, this could be a great marathon shoe. Not bad for a shoe that virtually disappears on your foot, in terms of weight and feel.
As a heavier neutral runner I tend to drift back and forth between neutral to (very) mild support in my shoe choices, and while this is by no means a stability shoe, the platform felt supportive and seemed to promote efficient transition from heel/midfoot to toe-off. High marks in this department as well.
Construction:
The upper felt soft and smooth on my bare feet, very sock-like. One major strip of stitching inside, but not likely to cause blistering due to it’s placement. The outer shell feels durable and not subject to premature breakdown. Very nicely done IMO.
The tongue is wide with straight-forward lacing, easy to adjust to accommodate anatomical variations. I had no trouble replacing the lightweight laces with elastic Yankz and adjusting to a comfortable setting.
The liner material is cotton-soft (along with the surface of the insole), which initially felt fine, but later managed to behave similar to cotton on my bare feet: after the sweat seeped in, it began generating a massive blister on my left heel. I’m fairly certain I can eliminate this problem with bodyglide or baby powder, so I’m not overly concerned about it, but I’ve never had that problem with other shoes that use a slippery liner like Mizuno’s. The insole is substantial as well, and has a surface similar to the heel liner, which feels comfortable under bare feet.
Concerns:
First, being that the upper effectively behaves like loose fabric, the insertion of Yankz laces causes the upper to cinch up completely when not on the foot, making a quick transition a bit tricky. Then, add to that the fact that the insole will grab on to a damp foot and crumple up into the toebox when trying to slide it on, and you may find yourself with an extra minute of T2 time on your hands trying to get them on properly. I suspect a spray-on adhesive under the insole may improve that situation somewhat, but between the yankz collapsing the upper and the potential for crumplization, I’m not convinced that it will ever be a quick-transitioning shoe.
Also, the last is curved, not semi-curved, and I found out just how different the two are around mile 2. I expected a racing flat to hug my foot more than my trainers, so when I tried them on in the store, I wasn’t concerned that the outside of my feet were up against the sides, however after a few miles, my middle toe began pressing against a solid element in the front of the upper which required me to curl my toes somewhat on my left foot to keep the pressure from ripping off a toenail. Somewhat surprising, but not totally shocking, was that the problems I encountered on the left foot did not present on the right foot (it sucks having two completely different feet). If the left foot was shaped & sized like the right, I could easily wear these shoes without any problems whatsoever; in fact, I’d probably run half of my miles in them if that were the case.
In summary:
As racing flats go, these are well-cushioned, comfortable, lightweight racers that would be ideal for road racers of most distances - provided you can wear a narrower, curved-last shoe. For triathletes with the same foot shape and neutral biomechanics, if you don’t mind risking an extra few seconds in T2, it’s probably a good choice as well.
After a minor modification to relieve the toe pressure, I’ll put some more miles down, work on solutions to the problem areas & post an update.
