Javier Mendezwrote a review of Inov 8 F-Lite 250 Cross Training Shoe - Men's on April 27, 2017
Familiarity: I've used it several times
You can tell these shoes are specifically designed for cross training (weights, cardio) with a simple look.
Every detail in the construction is optimized for that. For instance, the first thing I noticed is that they are incredible light (compared to my old running shoes)! The feel like cardboard. I was even worried they would not last since how could they possible be that light?
Anyways, the reason they are so light I presume is to make it easier to do box jumps or sprints (or pull ups, etc.. you get the point). So far I have zero complaints against that or their durability for that matter (been using them for one month or so). Other thing I like is the protection on the front in case you drop your weights. I've smashed enough toes to care for that.
Also, one detail is that these are not built to get outside - at all. Water passes through them as if you were wearing sandals. But that's a trade off for breathability, which is fine for me. Mostly a heads up in case anyone intended to use them for running outside on rainy days. They do dry fast, which I think is a side effect of such breathability.
