Mini-crampons for walking on icy roads and pavements

I've looked into buying mini-crampons for walking on icy roads and pavements, but the items I've seen for sale seem aimed at mountaineers, rather than the general consumer market. There must be a market for a simple single-strap (elasticated) crampon that has fairly short teeth, allowing walking on roads/pavements that have patches of ice. The long teeth of regular crampons would be a hindrance for most of the walking due to the only occasional patches of ice.
