Are you seeing a pattern yet? Yes, I am becoming a huge fan of the 6 year-old running shoe company known as Altra. As I have been instructing clients in form techniques, and have found that most of the models Altra manufactures, lend themselves to my favorite principles.
The Altra Impulse is no different.
What I like about the Altra Impulse
As with all of Altra’s models, my favorite advantage is their FootShape™ Toe Box. This is the incomparable wide toe box that Altra is known for. The toe box is makes any of Altra’s models recognizable from a good distance away. That is how wide it is. I enjoy the ability splay my toes and have my feet firmly hit the ground without them being cramped up. Wider toe boxes also allow the feet to develop more strength because the shoe is not tightening around the ball of the foot or the toes. The toes can move around, and tackle all kinds of terrain.
As you can see from the x-ray below, the amount of splay the toes are allowed in the Altra vs a traditional toe box. Imagine having access to the full splay of your foot while you run. What is amazing is that most runners do not even realize the limits that a traditional toe box causes. (Hmm, maybe there is an idea for a full post.)
The Altra Impulse is no different in this department. The FootShape™ toe box has been incorporated and has all the comforts of the other models I have run in.
I love the Zero Drop™ technology that Altra incorporates. When I run I have the ability to utilize the full power and flexibility of my calf not to mention I can run as if I was barefoot, as our bodies were intended. Most traditional running shoes have a 12mm heel drop. This means that the heel is 12mm above the ball of the foot.
When we are barefoot, the heel and the ball of the foot are equal which is a Zero Drop™. This also helps with heel striking. Have you ever tried to heel strike while running barefoot? Even if you are a regular heel striker in shoes, it is almost impossible to heel strike while bare foot running. A huge effort has to be made to do that.
So, why runners continue to heel strike? If your heel is more cushioned in the shoe, then of course you will want to hit that area first. (Another post may be needed to explain a little more on this too…stay tuned.)
I love the Innerflex™ which are grooves at the bottom that create a more flexible sole.
One of the huge differences with the Altra Impulse is that they also incorporated their patented StabiliPod™ technology along side the Innerflex™. Now you have a stability shoe that is also somewhat flexible.
I have decided to put this feature as a liked feature more for others than myself. As a pure neutral runner I prefer to work allowing my body to support me, not my shoe, but Altra is marketing this shoe not only for running and triathlon, but for cross training as well.
The StabiliPod™ technology does really help in moving laterally, which is not something that is usual for runners, and especially those of us whom usually stick to the pavement. This is why I do like this feature.
My absolute favorite feature of this shoe are the drainage holes in the sole. My very last test run with the impulse was an 8 mile run, immediately following a huge rain storm here in Tampa, Florida.
My route took me through numerous ankle deep puddles and while my socks remained damp, the shoe was clear of water within a few yards of the puddle. There was no squish from the sole of the shoe or my sock because as my foot pushed down on the shoe, the holes squeezed water out the holes. No more blisters from soaked uppers and water log socks release water as well.
The Altra Impulse also continues with Altra’s A-Bound™/EVA blend compound which sits directly under the foot and adds a return of energy and reduces ground impact.
The upper is a light material and does have a noticeable difference from the other models. The tongue and laces are curved with the shape of the shoe which differs from the straight tongue of traditional running shoes.
I actually enjoyed this new feature. The fit of the shoe felt more comfortable with the tongue falling in the same curve as my foot.
I rarely run without socks, but I did end up having to do go out for a couple of miles one day without socks, and they were extremely comfortable. While the upper is not seamless it is very close. There are only a couple of seems that surround the tongue, but they are covered with a light fabric that helps reduce any friction.
What I wasn’t so crazy about
This is probably a very individual issue, but even though I sized up to a 10 from a 9 and a-half, after a few miles my toes still ended up moving forward till I they hit the front of the shoe. This probably has to do with the fact that I only lace my shoes tight enough to lock in my heel.
If you like your shoes laced up tight this probably will not be an issue.
The price point for the Altra Impulse is $120 dollars, which while competitive in the market place it still is a little expensive. In this day and age where people are scrounging for liquidity, I really would like to see at least one company come out with a quality shoe that retails for under $80. Of course that is my opinion and my opinion only.

Which model do you like best?
Last weekend I participated in the Paint Wars Mud Run in Oldsmar, Florida. Well, mud run is not necessarily an accurate term, most of it was just wet, but it was fun. The obstacles were more nature made with some added ropes for safety, some hay bales and of course paint.
When registering for the run I was taken in by the description of the race which was, of course, a little exaggerated. The paint was to be squirted by Paint Ninjas at a lot of different points in the course. I only came in contact with two, but the anticipation made it fun. Let me start at the beginning.
I drove into the Whispering Oaks Horse Ranch with my little Mini Cooper Clubman where a volunteer pointed me in the right direction of the parking lot. Thank goodness I was driving my little car, because I ended up having to make a spot down a dirt road, but it just added to the suspense of the run. Upon following the signs to the registration table, we, Sarah and myself, were told to sign a waiver for the property, ok no problem. As we made our way to the registration line however we were then told to sign a waiver, this time it was for the race. One waiver for the property and one for the race? Whatever. We then got into a line for the registration and goggle pick up. It didn’t seem all that long, maybe 10-12 people, but it took almost 45 minutes to get through it. When we finally had a names checked and were given a SWAG bag with two promotional flyers in it, we moved over to the t-shirt line where we gave the volunteer our sizes. The next words out of his mouth floored me. “That will be 38 dollars.” What? Really? For a cotton t-shirt? Yeah, thanks but no thanks buddy. We went back to the car to drop off our phones and bags and headed to the start. We did receive a decent introduction to the course, basically letting us know that there was a few river crossings where if we decided to take them, we should know how to swim, because the depth was not shallow. At that point, my progressive 4b friend Sarah and I, took off at a decent pace.
It started with a trail run for about 500 yards and then a dead stop to wait for an obstacle. A tree crossing where the tree was underwater. I guess a lot of people took there sweet time, but Sarah took it like it was not even there and I just a tad slower. (Sarah is about 18 years my junior, so give me a break.) The crossing ended with a steep climb both up and sideways, with the recent rain adding to dirt making it a little slippery. Sarah was nice to her old partner and waited up a bit. I didn’t fall but I realized my agility is a little less than I would like it to be. (I think I need to get back to boot camp. As a matter of fact all the way through this course I was thinking that.) The next couple of obstacles were through the trails over trees and up hills till we came to another stop. We actually couldn’t see why we were stopped until we reached the top of this hill that then returned back to sea level, but in the middle was a rope swing that dropped you off into the water where you then swam about 100m to the other side with a strong current that could definitely keep you from reaching the exit point if you didn’t have some sort of skill. I think I had just enough.
I will say I wore my New Balance Minimus’ during the race which didn’t hold much water, but I think I might have been happier with the five fingers. The minimus’ would be great for Tough Mudder where there isn’t a lot of hill climbs, but here I think I would have liked the extra traction my toes would have received, but I digress.
After the swim there was a nice trail run with only a couple of puddles and a few hay bale hurdles to include a run through the ‘WAR ZONE’. OOOOOHHHH….we thought we were going to get it bad, we actually wore white so we would get it bad, but…nothing. Not a single Paint Ninja anywhere. SOOOO disappointing. Oh well, we kept running and a real nice pace. Sarah is has ridiculous stamina and while I was right on her tail the whole time, I was starting to feel it, luckily we hit another line for another tree crossing. This one was elevated over the river. We crossed that with ease and headed through another long trail run, through the war zone again, and with the same result, no Paint Ninjas, right into the one and only mud obstacle where our shoes got muddy, and it sprayed a little on our legs, but that was it. We crossed the finish line and went to the beer line.
We got in line and saw that athletes were paying 3.50 and we both decided to forget it. We found the cooler with gatorade had a couple of dixie cups and headed back to the car.
Was it fun, yes, but I wonder was it because of the race or because I had a partner who was very enjoyable to run with. I am going to say the latter, or maybe a little of both. Sarah said this was her break from studying for the third test out of four for her CPA. Sarah if your reading this…thank you for inviting me, thank you for running I had a great time, and I really hope you were extremely successful on your test.
