This project was on demand of Öllöv in cooperation with AB Halmstad Gummi Fabrik. Öllöv made their first version of this rubber shoe, Öllöv Original, in the 90’s and has since then been improved, the newer version is called Öllöv SoftStep. There is a lot of money involved in the equine sport, and the horses depend on the quality of the equipment. Using wrong equipment may lead to injuries. In this project the friction from the Öllöv SoftStep has been examined to obtain support in the theory that the Öllöv SoftStep promote the natural movement of the hoof. This was made possible by two different tests and where compared to steel shoes and the unshod hoof. A test focusing on the coefficient of friction on concrete and asphalt and another test that examine the slide- time and length of hoof in motion on concrete and fiber mixed sand. By comparing the results from the friction test to earlier reports shows that the coefficients of friction from the Öllöv SoftStep are between -23% to +14% comparing to the unshod hoof. The steel shoe coefficient of friction is -53% to -32% lower than the unshod hoof. Summarizing of the friction tests state with the fact that the friction from Öllöv SoftStep mimic the unshod hoof, by giving the horse traction to the ground similar to the unshod hoof. Results from the measurements of movement proves that the Öllöv SoftStep are closer to the unshod hoof in terms both slide time and length. This rubber covered shoe differ in a range 1-3 ms and 1-3 mm from the unshod hoof. The steel shoe differ in a range 6-18 ms and 3-35 mm from the unshod hoof, depending on horse and ground. This does not include extreme divergent values. The conclusion of this study results in the fact that the Öllöv SoftStep mimic the unshod hoof.
