The Muscle Runner "works The muscles, the calves, the posterior side without me really thinking about it. So that's great
for development of athletes understanding where they need to plant and where the force comes from. And also an elite athlete who just want to train and offload the body some,
but stay in that right position.... I can see these being perfect for 250s, 300s, 150s. But once you get going and it is putting your body in the best position [and strike] under the center of mass and striking the ground from your forefoot.... This takes away the amount of effort you gotta spend on trying to just put your foot in the right position. like, I feel like I did 200s in these, doing some part of the season versus the spikes, It'll be less wear and tear on my body."

"The Antepes Shoes Have Been Revolutionary For My Practice"

Footwear for targeting the Plantar Fascia & the Achilles tendon:
Antepes high-performance footwear double up as a rehabilitating tool for strengthening and elongating the fascia and muscles in the lower legs, such as the Achilles tendon and the Plantar fascia ligament, by loading and stretching those connective tissues through facilitating the ground impact being absorbed through the forefoot and allowing the body’s natural suspension system, i.e. the kinetic chain, to be activated at contact point and distribute the impact through the body’s musculature as opposed to the body’s joints, such as the ankle, knee and lower back. Antepes footwear boost a forefoot stack height that elevates the forefoot above the heel and into a dorsiflexion of between 10-15 degrees and allowing the ankle complex to enter its end-of range-of-motion and thereby work through its entire range-of-motion for maximizing muscle and tendon activation and building strength and elasticity over its entire operating bandwidth. The full length carbon fiber plate is curvature-form-fitted to the foot providing great arch support and helping pivot the wearer onto the ball of the foot and activating the arch’s musculature, including the plantar fascia.

"Best Running Shoes For Sprinting"

The Muscle Runner keeps the tension and load on the Achilles and allows for a snap-back to return the most energy for faster speeds.

They train the Achilles and calves and help with improving the stretch-shortening cycle by training the Achilles and calves over their entire Range-Of-Motion (ROM) by activating them within their End-Of Range-Of-Motion (End-Of ROM)

By Training with the MUSCLE RUNNER you'll benefit from the following due to the increased muscle engagement, calf & tendon extension:

1. Improving your running & training form - Form is First

2. Adding another element or skill to your abilities

3. Strengthening the less used & underutilized muscles

4. Preventing overuse and focusing on underutilized & quick-twitch muscles

5. Laying a Foundation to success by enhancing your running training and workout drills by adding extra dorsiflexion and extension of the calf muscles and the Achilles tendon

5. Repetition Leads to Injury (RLTI) Mitigation: Preventing overuse by training underutilized muscles that lead to enhanced performance
