Yep, HS is right. You want something with a heel lift if you want it specifically for weightlifting. I got
ridiculously expensive ones that are complete overkill for my skill level, but I feel like a baws in them. That and it keeps traffic coming to my log as Johnny Ryall comes into drool at them.
Though i do see a few people wearing that brand around the gym - particularly crossfitters. Depends on your goals i guess.
The link HS posted is a good source of info, and
Wei Rui warriors are a reasonable price with good reviews for squat shoes. They should be back in stock soon. Or the adidas powerlift trainers are another good option
