About Powerlift 4 what I read
here is that they stop to hold a load (becoming squishy) after some threshold (something above 200-250 kg barbell), and thus considered "entry-level". I wanted to get the shoes "for life" though, and I feel I might cross this threshold a lot sooner. But considering a price, maybe during those years I'll progress to the threshold there will emerge something more suitable
Another reason is being "entry level" the exterior looks not so durable as i.e. mentioned Romaleos 2. I understand that likely I will end up with Powerlift 4 though (while wanting Romaleos 2 instead, hence my question about how "wrong" it is to have a 0.75" heel)
