The 10 Best Slant Boards

If you're looking for something light and compact that's easy to take on the go, consider the OPTP Foam (around $23), which come as a pair weighing less than a pound. However, note that they do tend to lose their shape over time with frequent use.

The versatile Balance 1 Multi (about $37) massages your feet as you exercise, and when turned upside down, it can be used for support during back stretches. The legs fold out and fit into four different slots on the bottom, making it a breeze to change the angle.

Built from resilient ABS plastic, the StrongTek Wedge has a textured surface to prevent your feet from sliding, and cushioned lips for your heels to rest on. Unlike wooden models, it's easy to wash if it gets dirty, and comes in at a budget-friendly price of less than $35.

The Core Prodigy Calf Stretch (about $40) has a support strap attached to its base that helps you to balance during difficult exercises. Three strips of grip tape across the surface will keep you from sliding off, and at 12 x 16 inches, it can accommodate just about any foot size.

Boasting a heavy-duty steel construction, the Yes4All Premium (about $52) is both durable and sleek looking. It can be adjusted to angles of 20, 30, 35, and 40 degrees to accommodate different fitness levels and physical therapy exercises.

The Flybold Non-Slip (about $62) comes bundled with a spiky massage ball and a resistance band that can add a little more complexity to stretches and exercises that no longer challenge you. Plus, with a weight capacity of 450 pounds, it's stronger than most other models.

If safety is your number one concern, take a look at the Liberty Imports Wooden (appx. $56), which comes with four metal bolts that lock it in place once you've adjusted it to your desired angle, so you can be sure it won't collapse during your workout.

The StrongTek Incline (about $70) is the same size as the models used by physical therapists, and its 16- by 18-inch surface gives you enough space to stand with your feet shoulder-width apart, allowing for a wider range of stretches and exercises than smaller options.

Handmade from sturdy plywood with a birch veneer, the Rolling With It Adjustable (about $60) is built to last. It's been stress-tested at multiple angles to ensure that it can safely support up to 300 pounds, and it folds down to just 2.5 inches thick when you're not using it.

Featuring a quick-adjust locking system, the Liberty Imports Professional (about $60) can be used in five different positions, from a 15- to 35-degree incline. The entire top is covered in a nonslip surface that keeps you in place without hurting bare feet.
