Brief summary: Foot lesions can be developed during hiking because of external factors. This makes it important to study the effect of hiking equipment on lesion development.

This study analyzes the extrinsic factors involved in the appearance of injuries at the feet during the realization of a route of low difficulty and short travel. 33 participants wore cotton not technicians socks in his two feet, were used like control socks and 76 participants wore technical socks "Tierra" and "Set" one on each foot.

Detailed description: Socks it used as an indispensable element to protect the foot of injuries during sports practice. The different compositions of socks can influence the appearance of injuries. The technical socks are designed for high-performance sports use ("Lurbel" brand, models "Tierra" and "Set"), and non-technical socks (cotton) for everyday use. The socks had different composition: "Tierra" (50% regenerative, 25% cool-teak, 17% polyamide ions, 8% lycra); "Set" (75% cotton, 17% polyamide, 8% lycra) and cotton (98% cotton, 2% elastane). The technical socks had reinforced weave in the toe, metatarsal and heel areas.

Eligibility criteria: Inclusion Criteria:

* The admission criteria were: be of legal age, have no current health problems that would hinder or prevent participation in the hike, and carry a backpack weighing less than 3 kg. Participants were asked to use specific hiking footwear (light, flexible, soft-soled, with good grip and breathable material) (low top hiking shoes), based on earlier studies 38-40. They were also asked to do the entire hike following the instructions of an experienced guide and to not remove their footwear or socks before examination by a podiatrist.

Exclusion Criteria:

* Not meet any inclusion criteria.

Primary outcomes:
measure: lesions in foot developed during the hike
timeFrame: The development of the injuries in a single day of sport activity was observed: kilometer 0 of the route, kilometer 14.5 of the route and kilometer 29.6 of the route.
Secondary outcomes:
measure: Temperature
timeFrame: The temperature was measured in three occasions in a single day: kilometer 0 of the route, kilometer 14.5 of the route and kilometer 29.6 of the route
measure: Perimeter
timeFrame: The perimeter was measured in three occasions in a single day: kilometer 0 of the route, kilometer 14.5 of the route and kilometer 29.6 of the route
measure: Weight
timeFrame: The weight was measured in three occasions in a single day: kilometer 0 of the route, kilometer 14.5 of the route and kilometer 29.6 of the route
measure: Height at the start of the route for calculate "BMI"
timeFrame: The height onli was measured at the start of the walk in a single day: kilometer 0 of the route
