Testimonials "I have used and tested 7NAILTM for more than a year. In principle, I use 7NAILTM for all the new horses in my staple. The system helps to create a better hoof. A good hoof is very important for a trotting horse", says trotting horse trainer Flemming Jensen.  "7NAILTM can become a global success", says trotting horse trainer Axel Jacobsen, after having tested 7NAILTM over time. "For horses with broken hoof axes I often use 7NAILTM between the heel part and the shoe to limit wear and tear", says international show-jumping rider Thomas Velin.
