Protein kinase C mediates mutant N -Ras -induced developmental abnormalities in
2002
A rotatable traction pad for a shoe can be mounted in a circular cavity in the shoe sole bottom surface, with the cavity being relatively shallow in relation to the shoe sole thickness. The pad mounting mechanism can include an annular bearing housing adhesively bonded to the circular side surface of the cavity, and an anti-friction bearing carried within the annular housing. The traction pad includes a rigid central post that extends upwardly through the bearing.
