Hunnyboots widen at the top so that when the velcro strap is undone, you can just slip them straight off after a walk without having to undo the zippers. The zip is there purely to open the boot all the way to the toe nails so getting a boot on is simple. The velcro strap has been positioned to bring the boot in above the widening of wrist. This has been positioned underneath the dew claw so there's no contact at all, but they may be covered by the slightly wider fabric at the top. Hunny is very fussy about her dew claws and some other boots made them bleed and cut into her wrist. We designed with that in mind, along with toe nail space, so no rubbing of knuckles either. The profile of a Hunnyboot is quite low and the velcro strap sits well clear of a greyhounds dew claw.
