Study population: Individuals that ages between 18-60 (adults), healthy male and female

Brief summary: The aim of the study is, to evaluate and classificate the medial longitudinal arch height in adult individuals. Aged between 18-40 years,350 adults who are voluntarily participate is going to be evaluate with Feiss Line(FL), Navicular Drop(ND) and Longitudinal Arch Angle(LAA) in subtalar neutral and resting position. Maximum, minimum values are going to be calculated. The 95% and 68% prediction intervals will be used as cut off limits.

Detailed description: The aim of the study is, to evaluate and classificate the medial longitudinal arch height in adult individuals.

Aged between 18-40 years,350 adults who are voluntarily participate is going to be evaluate with Feiss Line(FL), Navicular Height(NH) and Longitudinal Arch Angle(LAA) in subtalar neutral and resting position. Maximum, minimum values are going to be calculated.

Participant's height, weight and foot length, from posterior aspect of calcaneus to the longest toe's tip, will be measured. Center of the medial malleolus, the navicular tuberosity and the head of the first metatarsal bone will be marked with a CD marker. With these landmarks in foot's relaxed position, neutrally, FL, NH and LAA will be measured by a ruler.

Feiss Line is a drawn line between the center of the medial malleolus to the head of the first metatarsal bone and then perpendicular line distance between this line and the navicular tuberosity will be drawn.The vertical line between the ground and the tubercle indicates Navicular Height. Center of goniometer placed at the navicular tuberosity then goniometer arms follow the medial malleolus and the head of the first metatarsal bone, degree between two arms indicates Longitudinal Arch Angle.

FL, NH, LAA mean values will be calculated. The 95% and 68% prediction intervals will be used as cut off limits.
