FAQ

QUESTIONS

ANSWERED

1. How do I choose the right size?

Select your standard shoe size at checkout. If you're between sizes or wear different sizes across brands, always go with the larger size.

2. Can I use Ultraform Lift for different squat variations?

Yes. It works across front squats, goblet squats, split squats and more. The strap keeps your foot secure regardless of stance or load.

3. Is Ultraform Lift suitable for heavy lifting?

Yes. Rated to 450 kg / 990 lb, with a rubber outsole and full-foot pressure distribution to keep your platform stable under maximal load.

4. Is Ultraform Lift beginner-friendly?

Yes. It improves depth, alignment, and posture from the first session, suitable for all levels.

5. What is Ultraform Lift made of?

The body is skin-friendly TPU. The outsole is rubber for grip and traction. The strap uses premium smooth-loop Velcro, low profile, durable, and clean in appearance.

6. Can I use Ultraform Lift barefoot?

Yes, it's designed for it. The open-toe construction allows natural toe splay and ground contact while maintaining full support.

7. Is it compatible with shoes?

Designed for barefoot/socks use, but it can also be used with minimal barefoot shoes.
