Default Knee pads

Hi guys,

One of the freshies in my league just bought these to use for roller derby: http://g-form.com/en/pro-xc-knee-pads.html
And I'm really not sure what to tell her. My first thought is that this isn't gonna work for roller derby, but I want to be sure before I tell her to get new ones. I don't really know anything about them.

Opinions? Can we just automatically exclude everything but the traditional roller derby knee pads we all know?

I advise the skater-purchaser call the manufacturer and get them to state they are engineered to handle derby duty. If not, all bets are off. Returnable?

The primary concerns are whether or not, on impacts, that they slide across the floor adequately well, without the amount of sliding friction being too grippy, causing body flipping, plus steadily damaging the G-foam.

Next is whether the G-foam's stiffen on impact response is fast enough, protective enough, and sturdy enough to handle the impact frequency and intensity that derby demands of knee pads.

I suspect they will come up short in multiple ways. A thin layer of harder plastic could be glued over the G-Foam to likely improve their derby performance, but that experiment would be a salvage operation, not an ideal solution.

I've only seen those from a distance. My initial question is what is the surface? There is a rule (in WFTDA) that states "9.1.2.1 - Wrist guards, elbow pads, knee pads, and helmets must have a hard protective shell or inserts." The reasoning is probably partially that soft knee pads (like volleyball) will not slide. If your knee goes to the ground and "sticks" while a large body pushes you from the top you risk a tear or dislocation aside from the direct impact.

The version of this I saw appeared to be squishy, which would lend itself less to sliding than a single plastic shell.

Even if you are convinced they fit the rule, do you think that a ref might have a problem? The rule says "a hard protective shell", and this design, even if it is hard on each individual surface may not fit that.

As mentioned, they would need a plastic shell to be used for derby. Also, the foam will stick to the floor and tear up quickly. But she could totally wear them as knee gaskets under a pair of traditional pads.
