Spursuaders are the most humane spurs on the market.  No rowels, and designed differently.  These are spurs only, no spur straps.  They are western made for western spur straps (one of the pics shows english spurs but it's for info only).

From the creator: “The reason I developed this spur was in large part my experience riding sensitive horses, particularly Thoroughbreds. How they overreacted to a traditional spur, how some would get tense right away when they knew you were wearing a spur or watching a horse get inadvertently “spurred”. That got me thinking that there must be another way to get our point across to the horse without offending or creating tension in that horse.”
