While TUV certification to standards such as 13992 is not the end-all be-all in knowing a product is reliable and performs well (real world testing is the only 100% truth, and TUV does not do extensive durability testing), it can be a good marker. The challenge in this is sometimes engineers will include a product “feature” that’s more motivated by receiving the TUV cert than any real life necessity. That’ll all come out in the wash this winter for Radical 2. For now, kudos to Dynafit for going to the effort and expense to obtain the TUV stamp.
Note that the TUV certification of tech bindings to standard 13992 and others is predicated on the use of Dynafit certified boot fittings. Don’t let that turn you off to boots that have third-party fittings (most are fine), but know that ALL boots need to be at least hand checked for smooth release, on the workbench, before you go out and ski your rig.
