Technology: Plastic horseshoes challenge iron in the sole

THE ANCIENT craft of farriery shoeing horses 鈥� has been thrown into turmoil by the arrival of the
plastic horseshoe. Farriers in Britain are having to come to terms with
a host of new designs, described in this week鈥檚 issue of Horse and Hound.

The trendy new shoes, which could soon come in a range of colours, take
advantage of recent developments in materials science. The manufacturers
claim they cut down the stresses on a horse鈥檚 tendons and joints, and provide
more cushioning for the hoof than conventional metal shoes and nails. The
spate of new designs from inventors across Britain includes polyurethane
shoes stuck on the hoof with cyano-acrylate glue, and shoes with a steel
base and interchangeable plastic soles with various treads. Britain鈥檚 biggest
selling plastic shoe comes from the company Mustad, which also claims to
supply 75 per cent of the world鈥檚 horseshoe nails.

Trainers and riders who have tried the shoes are impressed. For one
horse, the transition from conventional shoes to glued shoes was 鈥榓s dramatic
as if he had sprouted wings鈥�, the magazine says. But in last week鈥檚 issue
Chris Colles, 鈥楤ritain鈥檚 leading veterinary authority on the horse鈥檚 foot鈥�,
questioned claims made for the new footwear: 鈥楾here is no scientific evidence
that I am aware of that bolsters up manufacturers鈥� statements that some
alternative shoes absorb concussion.鈥�

A recent editorial also warned: 鈥楧IY foot trimming before sticking on
a plastic shoe is a dire prospect leading to wholesale deterioration of
equine feet.鈥�
