Hello. I have a pair of Northface Chilkats in a size 12. They're HUGE. According to your sizing guide for Katoola Microspikes for insulated Pac boots, X-Large fits Women's sizes 12+ / Men's sizes 11 - 14. But I'm concerned that the hugeness of the Chilkat will still stretch the x-large katoola. Do you know folks who've used these spikes on the Chilkat? Thanks!
