However, I've never "slipped out" of my Holdfast straps, so that hasn't been an issue for me.
I live on top of a hill in Santa Cruz, and that tends to place a special importance for me on foot retention. if i ever want to ride anywhere i have to go down a pretty sizable hill, so it is in my best interest to prepare accordingly. I've come un-clipped with both hold fasts, and toe-straps and neither are fun at all. Take my statements about both foot retentions for what they are worth to you though.
