Puma Electrify Nitro 4 Trainers - Gold - 3.5

These are primarily designed for road training and paved surfaces; they lack the aggressive lugs needed for technical trail running.

Use a soft-bristled brush and mild soap to gently scrub the fabric, then wipe clean with a damp cloth.

As a neutral trainer, it does not feature a medial post. If you have flat feet, you may wish to pair these with an orthotic insole.

The Nitro foam is engineered to provide a responsive, cushioned feel that absorbs impact without feeling heavy.

Yes, the provided insoles are removable and can be swapped for custom orthotics.

Try a runner's loop (lace lock) lacing technique to increase tension around the ankle collar.

The foam may require a break-in period of approximately 20-30 miles to reach optimal flexibility.
