Dallmer shoes

[Pete and Debbie LaBerge <plaberge@epix.net>]

A friend of mine who has an equine sports therapy facility showed me a
an unusual set of shoes that a competition driving horse came in with
that I had never seen before.

They looked like a Mustaad shoe with a sandal type apparatus so that 
the owner could put on and take off the shoe- a neoprene looking thing
that fit over bulb and then two sandal type straps coming off the
neoprene looking thing that criss cross over the front of the hoof and
are attached to clips on the front sides of the hoof. The shoe said
"Dallmer" on it and he thought they were from Europe. The horse wears
them in off-road driving events in all kinds of terrain. I think the
owner of this horse uses them on many if not all of his horses. I just
can't imagine how they would stay on or not cause irritation to the
bulbs.

Anyone know about these?
