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.
Sizing and fit questions
- Which UK size should I order?
- Order your normal UK shoe size. This listing covers UK 5/6, 7/8 and 9/10, and every pair is trimmed to fit, so if you fall between two ranges take the larger one and cut it down.
- How do these compare to other sizing standards?
- UK sizing runs about 1 size below US men’s and 5 sizes below EU (UK 8 ≈ US men’s 9 ≈ EU 42.5). All four listings are the exact same patented 3/32-inch Springbak® Springsole at $29.95 — only the size scale printed on the package changes.
- Will Springsoles fit football boots, rugby boots, trainers and golf shoes?
- Yes. Pull the factory insole out, trace it onto the Springsole, cut just inside the line, then drop the Springsole in first and put your original insole back on top. At 3/32 of an inch, football boots, rugby boots, trainers and golf shoes keep their normal fit.
- How do I check out and what if the size is wrong?
- Choosing a size here opens the secure Springbak® cart on springbak.net with this listing and your quantity already added. Payment, shipping and exchanges are handled there by the Springbak® team — email info@springbak.net or call 951-277-3000 and we will get you the right pair.
