The Training Shoe That “Fits Like A Glove”


Nike’s TR Fit III training shoe for women achieves an amazing fit with Ariaprene’s alternative synthetic foam

The shoe description says, “Engineered foam construction. Asymmetrical internal structural support system for multi-directional movement.”

But the online comments from women who’ve actually worn the shoe are a little more effusive, with statements like, “I love these shoes! These are like gloves for my feet.”

When the Nike Free TR Fit shoe was developed for women, Nike wanted to create an upper that would hold the foot enough for vigorous cross-training, yet fit so well that wouldn’t cause blisters even after long workouts. The design called for a flexible material that was both lightweight and strong. And the material they chose was Ariaprene.

Not only did our alternative to synthetic foam meet their rigorous specifications, it also met their goal of using non-toxic, green materials whenever possible. Ariaprene is free of toxins and solvent adhesives, dramatically lessening the environmental impact of the shoe.

Now three product generations later the Nike Free TR Fit III continues to be a best-seller because of its comfort and performance.

We’ve been making Ariaprene for more than eight years, using a patented solvent-free process no other manufacturer can match. And Nike is just one company that’s recognized how Ariaprene can help them to meet their environmental goals while simultaneously producing products with superior fit and performance.
