I'll take a stab at the 200$ vs 60$ question.
That $60 dollar shoe, the 'leather' upper to just sewn or glued to the simply flat bottom sole.
Also, that Powerlift 4 appears to have to EVA? (foam) bottom, its actually just a tad squishy.
EDIT: googled it, it IS actually called "foam" ... "EVA High Density Foam".
'Foam' doesn't sound good to me for a heel structure on a Weightlifting shoe.
You can actually push your finger (nail) quite aways into my Powerlift2s....it appears the 4's are the same.
That $200 shoe, the sole is worked into an rigid part of the lower, that comes up and encapsulates the bottom part of your foot a bit.
Kind of like the Romeleos2 heel cup.....all that hard plastic comes up and around your foot. Its very stable.
You can see it here:
It doesn't look like much, but then also the inner part of the sole is dished out for your heel, and similarly formed for your arch.
These Weightlifting shoes have really hard dense plastic bottoms/heels. There is no compression there.
That is the main difference between those shoes.
I would not recommend Powerlifts based on my Powerlift2s (its appears they've only changed cosmetically).
They are a good shoe to buy to take to a cobbler chop up into a zero heel drop deadlifting shoe though .... because they are $60 and are so simply constructed.
