personally I cant live without a foam roller and my therabands.... I get injured so often its unbelievable. I have a penchant for falling over, slipping, walking into radiators and pillars, tripping over, and falling down stairs so I have to keep stocked up with my own physio equipment to sort out any niggles myself so I don't have to wait 3 weeks for the referral to go through or pay £40 to go private for one session with the physio. But if you haven't got the inner ear equilibrium of a drunkard like I do, I'd probably say a decent pair of trainers given to you after a running expert tests your gait. Good footwear is essential in stability,shock absorbation and microreflexes. Even if you aren't running,in a workout wear running trainers, they'll hug your ankles enough to allow rapid movement and keep you from straining anything, provided you have good form. Don't just wear any old nike high tops to the gym like some idiots do. None of those boxing high tops either, they're for boxing and don't provide much room for dorsal movement. How many boxers have you seen wear those shoes outside the ring? none.
