Train

Training programs built around the half-second your foot spends on the ground

28 complete blocks — speed, vertical jump, agility, rotational power, foot and ankle resilience, balance after 55, and a full off-season plan. Every one names the number it moves, the phases it runs in, and the tests that decide whether it worked.

Start with the number you want to move

Pick one goal

One block at a time. Each program targets a single measurable outcome — a 40 time, an approach jump, a shuttle, a sit-to-stand count.

Test in week 1

Record the tests listed on the program before you train a single session. An untested block is an opinion.

Keep the surface constant

Same shoes, same surface, Springsoles installed from week 1 to final testing, so the only variable left is your training.

Why every block starts at the ground

Two films from the Springbak® archive. The first shows how the patented material works under an athlete's foot through running, jumping, lifting and cutting. The second, filmed at Northstar Studios in Nashville, opens with BYU track and field head coach Mark Robison and follows six years of R&D with the athletes, coaches and researchers who tested it.

How patented Springbak® technology is designed to work beneath the athlete's foot during running, jumping, lifting, and cutting.

What Springsoles are. Opening look at the Springsole itself: a 3/32-inch patented energy-return layer fitted under a removable liner or on top of a firmly bonded or stitched liner.
0:55
Energy return under the foot. How the patented material loads on ground contact and gives that stored energy back into the next push-off, instead of absorbing it the way soft foam cushioning does.
2:10
Sprinting, jumping and cutting. Athletes running, jumping and changing direction, with the ground-contact phases where a sprinter or jumper is asking the most of the shoe.
3:35
Install and fit. The install shown uses a removable liner: first try the Springsole untrimmed, then lift the liner, place the Springsole underneath and reinstall the liner. Trim only the toe or forefoot in very small amounts if needed for a flat fit.

The Springbak® Legacy Film

Filmed at Northstar Studios in Nashville: founder Bill Crow's vision, six years of R&D, and the athletes, coaches and researchers who tested it.

Coach Mark Robison, BYU track and field. The film opens with BYU track and field head coach Mark Robison on what he saw when his athletes trained and competed in Springsoles.
1:10
Bill Crow and the original idea. Founder Bill Crow on the idea behind Springbak®: put a thin spring plate under the foot so the athlete gets energy back from every step rather than losing it into the shoe.

Six years of R&D and lab testing. The development years — material iterations, and the university lab work behind the balance, stability and stride-analysis results published on the proof page.

Coaches and athletes on the result. Coaches and athletes who tested Springsoles across track and field and other sports describe what changed in training and competition.

Patents · force plate tested

The platform under every program

More than twice the force

Force plate testing at Weber State University found athletes wearing Springsoles required more than twice the force to be displaced from a standing position.

3/32 of an inch

Thin enough to fit under a removable factory liner or on top of a firmly bonded or stitched liner in a spike, court shoe or walking shoe.

Force-Plate Stability Study

In force-plate testing, subjects standing on Springbak® Springsoles showed more than twice the overall resistance to being pushed from their position.

In plain English: they were harder to move. They could hold their ground better against a sideways push—exactly the kind of stability athletes need when planting, cutting, jumping, landing, and absorbing contact.

Springbak® gives the foot a more stable, responsive platform to work from inside the shoe.

Results are from the force-plate testing described in U.S. Patent No. 6,589,630 B1. Individual results vary.

Training program questions

Which Springbak® training program should I start with?

Pick the block that names the number you want to move. If you want a faster 40, start with Speed & Acceleration. If you want inches, start with the Vertical Jump Block. If you are in a competitive season right now, run In-Season Strength and wait for the off-season for the rest.

Can I run two programs at the same time?

Run one primary block at a time, and only stack Foot & Ankle Resilience alongside it — that block is deliberately low-fatigue. Everything else competes for the same recovery.

Do I need Springsoles to use these programs?

No. The programs stand on their own. Springsoles matter because every block is built around ground contact: install them before week 1 and keep them in through final testing so every number you record was set on the same platform.

How often should I retest?

Test in week 1, at the mid-block checkpoint listed on each program, and in the final week. Testing more often than that measures fatigue, not progress. Log the numbers in the athlete tools.

Are these programs appropriate for high school athletes?

Yes, with a coach supervising the barbell work. Each block lists a level; where a program is written for collegiate athletes, cut the weekly volume by a third for high school and keep the intensity.

What is the research behind the Springbak® guidance in each program?

Force plate testing at Weber State University found athletes wearing Springsoles required more than twice the force to be displaced, and a treadmill stride analysis at USC examined stride mechanics. Both studies, and the four U.S. patents behind the design, are documented on the proof page.

Install once, then run the block

One pair, made in the USA. Fit them according to each shoe’s liner type before week 1 and log every test in the athlete tools.
