I have tried Kathoola (SP?) micro spikes and was less than impressed as they would "walk" around my boot after extended sidehilling.
The Cypress 6 from Hillsound ratchet down tight and stay very secure.
I picked these over some other options as I like the fact that they don't have the crampons off the front of the boot. That way I don't get hung up as much when going up hill through the brush and grass, likely not an issue if only on the snow, but things are pretty varied vegetation wise on our Alaskan goat hunts that rarely go above 4K'.
Just another option:
Cypress6 - Crampons for Winter Footwear Traction- Ice Traction - Hillsound Equipment
On winter mountain goat hunt in February, no snow at sea level but plenty once we got to elevation:
