My horse is currently in glue ons (Polyflex) and was in them for several years (we took a short break from them due to an injury).
There is an option with stud holes, but we’re just getting back to eventing after spending the last 4-5 years in jumperland, so I don’t feel a need to use studs yet.
My horse does really well in the glue ons. We have no issues with traction or slipping, and he can’t pull them off like he could with a standard nail on shoe. He’s more comfortable in the glue ons than standard nail on shoes, nail on shoes with pads/Equipak, etc. They do offer some pad options, but I have no experience with them.
The only downside is the cost, they’re significantly more $$ than standard nail on shoes, but having my horse be a lot more comfortable and not worrying about sprung/lost shoes is worth every penny, 10/10 recommend. Application is KEY. Glue failures happen because they weren’t put on properly. My horse goes out every single day in every kind of footing, snow/ice/mud/hard+dry/grass with no issue. Not every farrier can do glue ons well, just keep that in mind.
