Then there is a total change in the front of the boot.
The front of the boot is definitely different. Looks like it should snug right up to the hoof wall. A slight issue on the old pair was getting that boot to conform without over tightening the velcro. I think this may remedy that. We'll see!
The other change I see is in the captivator itself.
It looks much more protective and I'd think less likely to snag on a stick or rip on a rock.
Now let's talk tread...
The tread looks somewhat more aggressive and the hear-say is that it wears longer than the old boot tread.
Sizing on these was metric. So you either measure in mm or convert.
They sure are pretty! Don't think I'll lose these in the black hole I call my boot box.
Next step! Try them on the Spotted Wonder.
