Is the ForeverRun Nitro 2 a stability shoe?

Yes. The RUNGUIDE guide rails add support aimed at overpronation, so it is a cushioned stability trainer rather than a neutral shoe.

How does it differ from the original ForeverRun Nitro?

The Nitro 2 keeps the NITROFOAM midsole and RUNGUIDE system and updates the engineered mesh upper, which uses at least 30% recycled materials.

What is the outsole made of?

A PUMAGRIP rubber outsole, which Puma rates for traction in both wet and dry conditions.

Does it run true to size?

It comes in a regular width across women's sizes 6 to 11. Most runners take their usual running-shoe size, but try it on if you are between sizes.

Can I use it for walking or gym training?

It is designed for running and everyday training. The stability rails suit road running best; for gym work a flatter cross-trainer is a better fit.

How does it compare with the Brooks Adrenaline GTS?

Both are cushioned stability trainers that guide the foot through a support system rather than a firm medial post. The ForeverRun uses RUNGUIDE rails and NITROFOAM, while the Adrenaline GTS uses Brooks' GuideRails and DNA Loft cushioning, so the choice comes down to which ride and fit you prefer.
