Not a big fan of orvis boots, but thats me. I think those are new, so not sure how many people may have had the time to really evaluate. If you're wondering about the zipper, I really don't see the big benefit, you'd still have to loosen and tighten the laces when putting them on - taking off I see the benefit. As far as the studs - again, not a big fan of screwing them into the sole. I've had some simms that required that and the screws fall out usually sooner than later. If the price is right, by all means get them otherwise I'd go with embedded studs.
