I notice the slip in these when walking, but not so much when running. I do have to tie a bit tighter than I'd like to, though. The peaks are super wide/sloppy for me at the heel and I'll have to come up with something to take up some of that volume.
Yeah, the 'negative drop' feel is weird at first, but it goes away after a few days
