a simple foot rig

i 'm trying to make a simple foot’s rig with 2 bones
just to bend the toes at the front see pci

so i made a vertex group a asign it to bone 1 but when i got into pose mode and move that bone
it looks like not all the vertices are stiking with the bones

how can i correct that ?


The problem is that the bone isn’t influencing those vertices. You should make the envelope bigger, add them the vertex group, etc.
