MORE ABOUT SMARTFIT™

Honest Pricing, Guaranteed.

Despite loving 2-for-1 avocados at the supermarket, we choose to price our products honestly 365 days a year. No gimmicks or discount tricks. No need to wait for a once-a-year blowout sale to treat yourself.

A STEP ABOVE.

We set out to create the most advanced footwear on the planet. Part of that mission is using technology and forward-thinking methods in our business practices. The result is less waste, overstock and middle-men – and savings passed on to you.

YES, QUALITY COSTS MORE.

Our products are made from the best materials on the market – finding harmony between quality, durability and performance. And every pair comes with a 2-year warranty to back it up.

IT'S WORTH IT.

We did the math. One pair of cheaply-made shoes lasts a few months. In just two years, you would need 4-8 pairs, spending upwards of $300. OR you could save time, money and the environment with one pair of Casca’s. Plus, great products at great value never go out of style.
