According to page 231, "If you are climbing, pulling, or pushing yourself along in micrograv, you move at half your walker Movement Rate (i.e., 4/20 becomes 2/10). You can also jump any distance, though you cross at a rate equal to your movement action when you launched."
Prehensile feet reduce base walker movement from 4/20 to 4/12 and are a standard feature of the Bouncer morphs (which simply include the modifier and have Walker 4/12). These morphs are intended for optimal use in micrograv, so why do they move slower in such conditions than flats and many other morphs?
Should the prehensile feet ware say that the speed reduction does not apply in microgravity? Or, perhaps they should instead allow full movement in micrograv (so 4/12 compared to 2/10)?
