The optimized reduction of leverage offered by the NB PLR & PLR Race is proving to not only be a superior tool for treating lameness, but also for preventing lameness and improving performance. The simple fact is that horses who are free of pain, thanks to a reduction in the amount of effort it takes to move, will perform better and stay sounder longer. That is what the NB PLR & PLR Race offers the performance horse. The Aluminum PLR shoe is made of a forged aluminum alloy that is heat treated for added hardness. This combination offers a light, yet durable shoe for optimal performance.
