Of course you can make up your own mind about running with ankle weights, but be aware that it may not be such a good idea.  There are a lot of intricate biomechanics involved in running and adding an unnatural strain to your legs while running is potentially harmful.   Running in and of itself is sufficient to achieve your fitness and performance goals.  I don't think it is worth risking an injury (and making an enjoyable activity less enjoyable!) to wear ankle weights.

The Dangers of Exercising with Ankle Weights

The additional effort that goes into exercising with ankle weights can actually make you weaker and more prone to injury. Ankle weights cause added stress to joints, especially the knees. Torn ligaments and pulled muscles in the calves, thighs, and ankles can also be caused by exercising with ankle weights. According to the Mayo Clinic, walking with ankle weights changes how a person normally walks. This destabilizes balance and increases the risk of tripping and falling.  An easy rule of thumb to follow is that ankle weights and aerobic exercises do not mix. Although ankle weights seem perfect for running and walking exercises, many health experts agree that walking with ankle weights is a risky activity.

By adding miles and intensity to your training.  Lots of dos and don't to help stay injury free here are a couple:

Good pair of shoes

Don't add more than 10% increase of miles in a week

After about 2 weeks of increases of miles drop back down in miles for a week then go back up the next week

Don't add speed work and increase in miles in the same week

Have fun

I recently did a gait analysis with a video camera to track my leg movement.  The difference between barefoot and wearing shoes, for me, when walking was striking when played back

The extra momentum from having shoes on my feet pull my feet out in front and cause a much bigger heel strike and over extension of the knee, and extra extension of the ham string.  My shoes are standard training shoes, so weigh less than 1lb each, and are probably too heavy for me!

yeah dont use the ankle weights for running  they can be used to help build resistance in cardio or walking but i use them as wrist weights
