Using old running shoes for track workouts

Yes, it's generally fine to use older running shoes for track workouts as the surface is easier on the shoes and your legs. However, it's important to listen to your body and switch to newer shoes if you start experiencing discomfort or pain during your workouts.

Track workouts should not use old running shoes. Running shoes lose cushioning and support with time, increasing injury risk.

Additionally, worn shoe soles may not provide enough track traction. To maximize performance and safety, update running shoes regularly.

I would tell those Adidas Adios, Adios! They are old and worn out. Not worth the risk to wear them to do a track workout in. Retire them to use around the house for painting, mowing the lawn, etc.
