Personal Practice:
Here's a couple thoughts about the SoleSteps®, coming from a coach. Understanding WeckMethod's three core functions (Coiling Core Training, Rotational Movement Training, and Bilateral Torsion Training), will unleash an endless amount of possibilities for athletic performance utilizing the SoleSteps®. The simplicity and immediate benefits are relative to every type of sport. Training unique moments, in different core postures, all best experienced through personal practice. Here are a few sports and how the SoleSteps® relate.
I often say, "using SoleSteps® is like bringing the pitching mound with you wherever you go". Pitchers spend their whole careers throwing and landing on a downhill angle, very often can they replicate that while they train away from the mound and in the gym/at home. Now we can with the SoleSteps®. Whether it's single leg RDL's, pistol squats, or split stance med ball slams, replicating the downhill angle for pitchers in balance with flat ground training is definitely a great way to make it more game-like. Strengthening the last part of the throwing action, the deceleration of that lead leg, at the specific slants/slopes of the SoleSteps® is key.
Fighters and Martial Artists spend the majority of the time on the balls of their feet. A continuous rhythm between Fight and Flight. Now consider leg kicks. The lead leg almost always plantar flexes and rotates through with the kick. It is a quick violent action and your ankles and bones in your feet should be prepared for that repetitive movement. Introducing simple techniques like weighted calf raises on the SoleSteps®to a fighter's routine will leave them having a greater range of motion and strength to initiate the lower half rotation.
Track Athletes: 
Understanding the basic principles behind Bilateral Torsion Training, we're able to utilize both the uphill and downhill facing positions on the SoleSteps®. When training accelerations angles for faster starts/ short distance track athletes, we practice exercises on the SoleSteps® with the Steps facing downhill. This allows us to train the anterior side of our core.  When we're training endurance/ long distance track athletes, we have the SoleSteps®facing forward uphill. This connects us to our lats and posterior chain. One of the best tips to get the most out of your SoleSteps® while training is placing them on top of one another. They create another solid platform at a higher slope/pitch that can be used to access a whole new range of motion for your ankles and feet.
