These are not as exotic or unusual as they get potrayed....they're just shoes.
Yes, they have a very pronounced lateral flange and, I probably wouldn't like them on hard court, but otherwise just shoes.
My feet are pretty medium, maybe my forefoot is a litter wider, but they fit me well.
The clay outsole is good, very sure-footed, seems like the herringbone is a little more spaced out which seems to help it release the clay and maintain grip.
Feel like some reviews say you "need good footwork" whatever but they're just shoes.
They're sort of minimalist in the cushioning but the uppers provide alot of lockdown and support, very sturdy. Good arch support too.
A little contrast to the SFX EVO that I am playtesting. Those have a fabric upper that is not overly stiff/supportive, quite a bit more minimalist, light, and forgiving in that it flexes/stretches. Great for larger, not just length, footed individuals. Of which it says they were designed.
Overall, if you can stomach the price, enjoyed Vapor 9.5/X -type shoes, give them a shot. Length is true for me, I wear 11 and these are 11, my feet measure medium but do taper out toward my forefoot, but not extreme like Fed's. I think more people could wear these than what you'd believe from reading reviews.
