I occasionally lift in my shox but I hate doing Olympic lifting and squating in them as they just feel too mushy (with the exception of the jerk where I can actually lift more with the shox!). I think court shoes, shoes with a firmer insole, or olympic weightlifting shoes would be the best bet. To be honest with you, since I started lifting in OL shoes, I find it tough to lift in anything else. But then again, squatting and OL is all I do. And btw, I’ve found that the shox do get progressively softer and softer with lifting (just as they would with a lot of heel-strike running and walking).
