The Under Armour Speedform Fortis is classified as a lightweight performance trainer. It is relatively lightweight at 238g and has an 8mm heel-to-toe drop.
Upper & fit
The upper is soft and remarkably comfortable, which was great for middle distance runs. However, I would prefer more structure to the upper for longer runs.
The tongue was constructed well, with sufficient thickness to prevent pressure from the laces while not taking up excessive space in the shoe. The shoe features an external heel counter together with a silicone rubber lining around the ankle to lock the ankle in place while running.
The shoe runs true to size, but those with narrow feet might have to size down half a size.
The Under Armour Speedform Fortis features a dual-density midsole.
The softer charged midsole (Black) is “encapsulated” by a firmer and more responsive Micro G foam (White). This resulted in an extremely unique and fun ride. The shoe is also flexible in the forefoot.
As for the outsole, orange rubber patches are placed in the centre of the forefoot as well as the heel.
The uncovered areas of the midsole wore out decently fast, with some areas of the outsole flattening out completely after 200km of wear.

Type of workouts
The Under Armour Speedform Fortis excels on the road. It is best used for tempo workouts ranging from 10km to half-marathons.
I found several issues with the shoe. Firstly, the traction was far from great. It was very slippery on wet ground, and lacked grip on trails.
Secondly, the sock liner was too slippery. Over distances of 10km, I almost always came away with a bleeding toenail due to my toe jamming into the front of the shoe.
I disliked the rubber at the heel cup. The original purpose of the rubber was to lock down the heel and prevent movement. However, I encountered blisters when I wore the shoe barefoot or with ankle socks.
Another dislike I had was that there is unnecessary weight at the heel. If one looks at the shoe from the top, it can be observed that the rubber at the heel is wider.
This was meant for stability for heel strikers or for gym workouts. However, as a mid-forefoot runner I found that this unnecessary weight could have been cut down further.
My biggest dislike was the breathability of the upper.
I am unsure if its due to the constant rubbing against the sock liner that generated a lot of heat, but my feet felt like they were on fire at the 15km mark of a half marathon.
The Under Armour Speedform Fortis is a moderately lightweight trainer suited for casual runners who want a fun ride on the roads.
Let me start with some quick specs for the Under Armour SpeedForm Fortis, heel height at 31.5, forefoot height 20.0 with a moderate heel to toe drop of 11.5. These shoes weigh in at 8.7 oz.
As a long time distance runner, the shoes I purchase have their work cut out for them. I never purchase shoes without research.
I will be honest, I am picky. Fortunately, I was not disappointed with the first fit on.
The Speedform Fortis is a very comfortable, lightweight, neutral trainer. These runners fit like a glove when sized correctly.
A nice snug fit is crucial when purchasing. While you certainly do not want a cramped toe box, having excess space will create a bulky feel to your run.
The stretchy, seamless upper is breathable and airy to allow excess heat to escape as well as quick drying for those wet situations. Though stretchy, there is sufficient support to keep your foot snug in place. For anyone exercising in low light conditions, the reflective outer assists in getting noticed by traffic.
A rare find
Speedform Fortis has a one-piece heel cup with a silicone rubber around the ankle to comfortably lock in your foot. This feature is critical for preventing heel slip and assist in preventing blistering.
As I am high mileage runner with tender Achilles tendons, these are one of the only shoes that do not irritate that issue.
The Under Armour charged have the new charged cushioning midsole.
That means, is it has both a cushioned and a responsive midsole. Most shoes only have one or the other. This shoe does both without sacrifice in either area. Very impressive.
For heel strikers, the midsole is very soft yet not bulky, as for the mid or toe strikers like myself, the midsole provides ample support, and the responsiveness is amazing during quick track intervals.
The integrated foam sole pattern also allows for adequate traction in most conditions. As mentioned, they have been successful in all types of terrain and Canadian true north winter weather.
From day one, these shoes felt like they were custom made for my feet. Here’s the kicker.
I have 650 kilometers on these runners, and they still feel like day one. My runs vary between asphalt and dirt road, and the soles on these shoes still have many miles to go. So far, I see no tears, rips, or uneven wear patterns.
I can’t overstate the reliability of the SpeedForm Fortis. Keep in mind I have worn these runners in all types of weather, from snow, salt, slush, rain, muddy trail runs, and the heat of summer. Still going strong.
I really want to see just how many miles these will take. Although I’ve already purchased a second pair in red and I’m constantly searching for old stock as this model has been replaced.
In concluding, I must say, I love these shoes, both pairs. Not only do they look amazing around town, but they are the most comfortable shoe I’ve ever worn. They are priced well, and top-notch performance no matter the training I’ve put them through, and they are amazingly durable.
From 50km training runs, to track speed work and any length of the race, even hitting the weights at the gym, this shoe checks all the boxes for me.
