Why gitzo skipped the spiked feet feature i don't know. Maybe they figured with global warming they're wouldn't be any ice in northern Michigan for their tripods to slip on.

$100 for the Markins add-on spikes for my Gitzo 1325 is outragous considering the price i paid for it. I've been using crutch tips slipped over the legs with 3/16 bolts as spikes but that's not 100% rigid. Has anyone drilled and tapped the feet and added their own spikes? Any other ideas?
AFAIK gitzo doesn't sell add-on feet for the 1325.
