Today was leg day and my new Reebok crossfit shoes arrived just when I finished working out... so... CRAP... but I did try them on for size and squat a little and deadlifted a little as well just to see... nothing really heavy or anything, I am still tired but I could noticed that even though these are not specific shoes for that (can't compare since I don't own any other weightlifting pair) they make a very noticable difference from any regular pair of shoes.
I usually work out in a generic "training" categorized shoe and I can tell there is a difference already... we'll see next time I have to smash my legs. For the price I bought them (almost -60% off) I am already delighted with what I got... maybe next week I will tell you more, or another kind of impression but so far, really really nice.
And it seems these won't get on the way of working any other body part... I think I will keep working out with my regular pair of shoes for other body parts but I don't thin these will be bad at all in case I wanted to use them. For cardio... well, that is a whole other story.
