The Power Trainer 4000 by Otomix is good all around shoe for multiple uses including bodybuilding and martial arts training.  Otomix has incorporated extra protection and support in the Power Trainer causing it to be somewhat bulky and “thick” feeling. Ultimately, it is a good choice if you are looking for a shoe for all sports, versatile enough for bodybuilding, weightlifting and Martial Arts training. But if you’re looking for a straight weightlifting shoe, there are better options.
