It was challenging to say the least.

So much so, that in the eight years since, Ive once again been at odds with running.

Designed with three layers of Lightstrike Pro foam, the stack is a whopping 50mm.

Currently, World Athletics Footwear Regulations require that stacks not surpass 40mm for elite road races.

Beyond the banned characteristics, the Prime X 2 Strung showcase a truly unique upper.

Its incredibly lightweight, not to mention breathable, both of which play a significant role in mid-run comfort.

Lets start with looks.

All in all, I dig the appearance.

I do, however, wish that they were sold in more colors.

(I still drool over the OGAdizero Prime X Strung Pulse Mint/Lucid Fuchsiapair.)

Of course,Im no sprinter or elite athlete.

When Im really booking it, I can run a mile in a little less than nine minutes.

Truly, I have never run more effortlessly.

Additionally, the minimal drop makes forefoot running feel natural.

Theyre not without downsides, though.

Walking in them can feel a bit unnatural due to the weight, height, and cushion.

Because of this, you may feel weighed down mid-stride, especially if youre sprinting and/or running long distance.

Now, to see if they inspire me to book my second half.

Only time will tell!
