Fillauer Obsidian Sprint Running Blade
The Fillauer Obsidian Sprint running blade is a sprint foot the maker recommends above all for distances under 800 metres. Its blade is split, which helps the runner hold speed and balance through bends and on uneven ground. It mounts on the back of the socket, an arrangement that helps athletes with longer residual limbs where build height is tight.

Who the Fillauer Obsidian Sprint suits
Made for competitive amputee sprinters with strong muscle control. Each blade is specified by body weight, so ordering, mounting and alignment go through a prosthetist, and exceeding the weight guideline voids the warranty.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.

Fillauer Obsidian Sprint: common questions
What distances is the Obsidian Sprint for?
Fillauer designed it for sprinting and says it is especially suited to distances under 800 metres.
How does the Obsidian Sprint attach?
It is posterior mounted, meaning it fixes to the back of the socket. That helps athletes with longer limbs who have little room for build height.
What warranty comes with the Obsidian Sprint?
Six months from the date of fitting. Using it above the weight it was built for voids the cover.
