The Rim (often called Vulcan RM / Roller Motion Rim) is a concave performance horseshoe designed to improve traction, breakover control, and hoof support while maintaining a lightweight sport-horse profile.

Roller Motion (RM) section helps the farrier place breakover exactly where needed.
Concave profile improves grip while reducing overall shoe weight.
Deep fullering creates clear nail placement and secure nail seating.
Higher inner rim supports easier medial/lateral movement and smoother transitions.
Convex radius inner rim reduces weight while maintaining traction.
Seated-out sole relief past the toe quarters helps reduce sole pressure.
Ready-boxed / safed heels simplify finishing and help reduce interference.
Versatile nail hole pattern allows flexible fitting across different hoof shapes.
Designed to fit around the coffin bone naturally, reducing reshaping time.
Available in front and hind patterns, with optional clipped versions.
Commonly used for dressage, hunters, jumpers, western performance, English show, trail, and pleasure horses.
Often selected for horses needing better breakover control, traction, and reduced leverage strain.
