I got totally tired of paying my farrier a zillion 
  dollars every 6 weeks, so I contacted the Xerox Palo Alto Research Center to 
  see if they could come up with a solution.  After 2 years of intensive 
  research and development, I'm pleased to announce the Turbo 
  Hoofalator.
   
  This remarkable product eliminates every single 
  concern about hoofs, shoeing, traction, angles, length, and padding.  
  Essentially, what we do is remove the entire hoof assembly and replace it with 
  specially built Hoofalator - just like an artificial foot for humans, this is 
  an artificial hoof, with all bio-mechanical functions self-contained within 
  the natural looking hoof assembly.
   
  All possible variations - hoof size, shape, length 
  and angles are individually settable.  The surface in contact with the 
  ground is a user-replaceable (with a screw driver) polymer, aluminum or 
  steel insert.  Since there's no hoof wall, there's nothing to 
  trim.
   
  Granted, these are a bit pricey (I figure it'll take 
  about 240 years to recover your investment), and your horse will have to go to 
  the Stanford School of Biomedical Research for the "installation", but this is 
  a very small price to pay for perfect, "never-trim" shoes.  Sure, 
  there'll be an impact on farriers, but they've been complaining too much 
  lately anyway.
   
  
   
  best regards,
