Ive always wanted to try running with weights in or on my shoes somehow. How do you attach weight comfortably? I can't imagine just taping it on and having it stay there for more than a lap... go to wal-mart and buy them, they come in packs, 5 lbs, 10 lbs, or 20 they are like anklets kinda. You can put them on your arms or legs. If you watch naruto, its like the weights that rock lee puts on to train.
