Abstract (en)
Footwear having retractable studs (22) that provide enhanced traction on slippery surfaces when engaged. A pull cord (38) attached to a plate within the sole of the shoe allows the studs to engage. The working parts of the shoe can be easily taken apart for cleaning or de-icing. An alternative embodiment of the shoe has a mechanism similar to that of a conventional ball point pen which is used to effectively engage or retract the studs.
