Overview
A plastic calf and ankle stretching device from ProStretch, listed in a Double size and weighing 32.4 ounces, sold as a single unit in blue.
The ProStretch design is a rocker-style platform that holds a calf stretch at a fixed angle, an alternative to wall or step stretches. The Double size designation points to a two-position or dual-angle stretch surface rather than sizing for shoe fit.

Who it's for
Useful for runners, athletes or anyone doing calf and Achilles stretching as part of a warmup or recovery routine. Not needed if calf-specific stretching isn't part of your routine.
Pros and cons
- Fixed-angle platform for consistent calf stretching
- Sold in blue with a Double size profile
- Lightweight at 32.4 ounces
- Plastic build rather than a padded or metal platform
Performance notes
The rocker platform holds the foot at a set stretch angle, letting the user lean into the stretch with body weight rather than holding a static position by hand.
