The aim of the study is to examine the kinematic parameters of individuals with pronated foot compared with individuals with normal foot

Individual with and without pronated foot will be recruited. Pronation will be defined according to navicular drop test. Inclusion criteria : individual who run on a regular basis at least 3 times per week for one hour, can run 5 Km in less then 40 minutes, without past injuries during the last year of Achilles tendon or other lower extremities pain.

Individuals will be asked to run for 5 Km in self selected velocity. The Milestone pod device will be used to monitor kinematic parameters.

functional test will be conducted before and after the running as follows: heel raise test and one leg hop for distance test.

Inclusion Criteria:

• running on a daily basis at least 3 times per week with minimum of 1 hour
• capable to run 5 km in less then 40 minutes
• willing to participate in the study

Exclusion Criteria:

• previous surgery in lower extremities
• Achilles tendon pain during the last year

the results of the study will be analysed. a paper will be submitted to international journal with study description including methods, examination protocol and results

following completion of data collection
