When we walk or run, our feet are able to land on the ground in whatever orientation makes life easiest for our hips, knees and ankles. When we're on a bike, however, our feet are at least somewhat held in place against the pedals. This can damage our leg joints, if they're forced to move in a stressful fashion. Germany's BioConform is now offering what it claims is a solution, in the form of its adaptable BIUS1 pedals.
First of all, there are already "clipless" pedals that feature a fair degree of float, keeping the shoe joined to the pedal while also allowing it to pivot around a bit as necessary. There are also, of course, non-grippy platform pedals that let the sole of the shoe slide back and forth – although it's always best if your pedals are designed to keep your feet from slipping off.
The BIUS1 features aluminum studs for grip, yet its spring-mounted design allows the pedal body to move around relative to its own axle. This means that the shoe stays in place against the platform, but the pedal can move in and out, twist to one side or the other, or tip forward and backward (like a regular pedal) in order to let the leg do what it wants.
According to BioConform, riders can choose to pedal using a skating-like motion. Additionally, besides reducing the risk of injuries, the pedals are also claimed to work a wider variety of leg muscles than conventional pedals, potentially allowing for more power.
BIUS1 pedals are made from aircraft aluminum, weigh 245 grams (8.6 oz) each, and feature Teflon-coated bearings. You can buy a pair for €225 (US$309) via the link below.

The only application of spiked platform pedals is on a MTB. As it is, full suspension riders don't need it by virtue that their fully adjustable shocks can much better control shock. Rigid frame rider usually have a suspension fork that take up much of the shock. Those with rigid forks choose to because of the precision, simplicity, light weight, and efficiency. I can't see these guys wanting to ride on pedals that wobble. Next, while riding seated, majority of the shock is transferred to the saddle, so the feet only really sense shock when riding out of saddle. In such cases, you had better be riding on the balls (or arches for some bmx and DH riders) in which case the calf muscles absorb the shock. Now explain to me again what's gained by adding more unnecessary moving parts to one of the primary human interface points? Do you really want your feet to slide and twist while hitting a rough patch of trail?
