Depends on how much you weight.
Personally, I wouldn't touch the squires in the park, but I usually ride 14, 15 or 16 DIN bindings. They are basically a lighter, lower DIN version of the Griffon, so they'll have the same issues as the griffons, and possibly more cause they're lighter (lighter usually means less material). Honestly, the Squire is really for people under 100 lbs in the park.
