Icebug Acceleritas5 Side View, Slightly Used ;)

Accelerating in Icebug’s Acceleritas5 RB9X. Running Shoe Review

Shoes are at least as exciting for the runner as they are for the stereotypical shoe-obsessed woman – if they are exciting.

Icebug’s Acceleritas5 are.

Where the Nike LunarEpic have an obviously different design and near-extreme sole, and where Icebug’s own Mist have their extreme-mesh upper, the Acceleritas do not immediately look special.

Lift them up, however, and you’ll notice what makes them special at once:
They are extremely lightweight, but their sole has lugs like hardly any other.

Step in, and it becomes clear that they do not only feel lightweight, they are also made to be like racing flats.

Flexible and minimalist, the Acceleritas5 fit like a glove (to the point where they do not even have an insole) and work very much like a “barefoot running” shoe.

So, yes, for both better and worse, you will feel every rock and stone and root on the track you take.

Taking these shoes for the first part of the Traunsee mountain marathon, thus, was quite a gamble.

There are very many sharp stones there, the “run” is often more of a climb – except when it isn’t – and this was hard on my feet.

At the same time, the feel for the ground was tremendously good, and that combined with the low weight of the shoes also provided benefits, making me more mindful and nimble, and thus faster.

Fast is also the key word.

With the “tractor tread” lugs on the sole, all made in Icebug’s highly durable and grippy RB9X rubber, the racing flat profile/cut of the Acceleritas5 isn’t the only thing that accelerates, there is also the “safe grip, free mind” of the sole profile and material.

Sure, I stumbled a bit on the loose gravel we have, had to be careful to try not to hit any sharp stones too directly and powerfully, but I felt and indeed was safe and fast. And it was fun.

It’s definitely not the fun of rolling roughshod over anything on your path, the way “maximalist” shoes allow you to.
For working on speed and agility, conscious of technique, however, these are easily the most special and promising shoes I’ve yet had the fun to use.

For tracks and trails, off the roads, not necessarily going the longer distances but dancing nimbly through forest, across meadows and over mountains, the Acceleritas5 are shoes to try.

I have used them a lot this year, have to thank Icebug very much for having provided me with them to try and review, and can’t wait to speed along in the Alps in them again.

In fact, out to present the Ambit3 Peak’s new route altitude profile and GPS comparison tracks between Ambit3 Peak and Spartan Ultra, even though there was some snow already, I still used the Acceleritas5…

When the weather turns yet “worse”, I might finally get a chance to finish trying out and then reviewing the Acceleritas’ BuGrip-spikes-enabled brethren, the Anima3…

And what's your take?
