You will not experience joint problems later in life from wearing weights. Everyone that says this is making shit up. They feel joint pain when older and find something to blame. Simple as that. Everyone seeks a scapegoat.
Go ahead and wear weights, and if you have an athletic program you run that's intelligent like what kneesovertoesguy has you do (you can find all his information available for free on Youtube.) then you will not have any problems with your joints at 100 years old if you continue the routine for the rest of your life. You have to use weights and you have to use high repetitions though. Develop your flexibility and strength in those far ranges of motion.
Working out with great range of motion is the only thing that will keep your joints young. Joint pain is normal -- being crippled is not. Don't get unnecessary surgeries and go train.
You can wear any weights on your ankles or wrists or shoulders and be fine, just workout.
