I’ve been getting a lot of queries lately from folks interested in starting to use Renegades or already using one model and curious about the other. My two favorite things about Renegades, and what ultimately led me to becoming a rep, are the ease of use and the forgiving nature of the boots. Let’s be clear: these are still a temporary hoof application, and as such you should be putting the most balanced, well cared for hoof possible into it. That said, both models of Renegades should slide on and seat easily, and retention is based on the flexing movement of the pastern and captivator rather than relying on pure snugness, so there is some accommodation in trim schedule and fit.

The release of the Viper model also means that there’s a host of new sizes for the not-quite-whole Original sized hooves, as well as more options for hoof and heel bulb conformation. To be sure, I can and do use both models on the same horse at times; this is not intended to be exclusionary information, but to paint the picture on some differences in the models and where you may want to look if you’re really fine tuning optimal performance fit.
Here is a factory provided side by side comparison of the two models.
The difference details break down as follows:
Original/Classic: Whole sizes: 0, 1, etc
Viper: *Length x width millimeter sizing
OG/classic: *Oval or “hind hoof” profile Viper: * ROUND profile, streamlined, wide quarters
OG/Classic: *generous undefined captivators Viper: *shaped caps to cup defined heel bulbs
OG/classic: *original tread Viper: *slightly more aggressive tread
To further illustrate, here’s a couple of my personal hoof photos that I thought demonstrated the model shapes nicely, sticking with Original on the left and Viper on the right.

Again remember that there is crossover, I’m not suggesting one shaped hoof couldn’t potentially pull off the other model, but since we’re chasing optimum fit generally, matching boot shape to closest hoof and heel bulb conformation just makes sense to me and the results are there for some clients with issues in one model that solved them when switched over to the other model– or by swapping captivators. Because yes, there is yet another step in the troubleshooting optimal fit train–the captivators! The generous Original cap or the defined Viper cap can be applied to either shaped boot shell depending on your needs, providing us with yet one more tool in the box.

This was a great post. Thank you for sharing.
So glad you enjoyed!
Great post, will refer people to it!!! 😀 Because I’m out in Renegades (both), I get asked and this is a really concise and clear explanation – THANK YOU!
It also helps me as I consider my next step in trying to get hind boots working for my young horse. (We all love hind boots, right?) Haven’t done much yet since he has such rock-crunching hooves but looking at getting more happening this year and best to be a ‘little’ bit prepared, maybe, lol.
Glad it’s helpful to you! I’m getting my youngster going in boots as well, she just did her first trail hike in all 4 Vipers 🙂
