XD Bockers Overall Brand Rating: NEGATIVE -
Skyrunner, PowerJumperz, Moonshoes, Kangaboots, this company produces the exact same jumping stilts under different names. They do not pay patent royalties to Alexander Bock and are accordingly Illegal to sell in patent protected countries. The company is notorious for tricking consumers into purchasing misbranded Jumping stilts. They'll have a site claiming their selling powerskips when in fact they're low quality knock-offs. Do not buy this Brand.

This brand has suffered from poor part and build quality. With weld breaks, stripped bolts and more. We have had group members Springs crack, and many members have reported their springs SNAPPING. In every other brand of Jumping Stilts springs snapping is near impossible. Due to how they're constructed, but in these they use poor manufacturing processes and do not care if it harms the user.

XD Bockers Model Rating: :(
This is the basic model. It's a copy of every other stilt. The above picture is just one. They also come in different color frames or sometimes look different in an attempt to mimic another brand and rip off sales. Don't be fooled, this brand uses poor parts.

Description from Skyrunner:

Skyrunner is defined mainly by a flat spring controlled upon deformation, so that the result is a straight movement relative to the ground. With the riser's functional principle, depressive spring characteristic and backward movement of the force point during deformation are achieved. This supports the natural force point movement in the heels direction at higher loads and allows the runner to transpose his optimal jumping energy. Hence, you can really fly!
