Size and fit

The Under Armour Syncline is a low-top hiker with a firm yet thin upper that cuffs the foot snugly. Unique to this shoe is the BOA speed lacing system that provides a quick and easy locked-in fit that won't lose tension in the water. This shoe is flexible to give the wearer freedom of movement when transitioning from and to the water.

Under Armour Syncline's high surface traction soles

Designed for dry and wet surfaces, the Under Armour Syncline hiking shoes are equipped with high-traction soles. They feature dashed lugs that bite into slick rocks, sand, and other surfaces.

Under Armour Syncline outsole

Tackle the challenging terrain with EVA lightweight foam

For the midsole, this shoe uses EVA - a lightweight foam that is known for its durable cushioning, impact absorption and bounce rate. Another interesting characteristic of EVA is flexibility.

Under Armour Syncline midsole

Provides optimum breathability and durability

The Syncline has an upper made of dual-layer mesh which is designed for optimum breathability. The internal structure of the shoe has welded TPU overlays for added durability, support, and abrasion resistance. 

Under Armour Syncline upper

Provides water protection

There are drainage ports along the sides for efficient drainage of water. Unlike hiking sandals, this shoe provides toe and forefoot coverage, protecting your foot against sharp objects in the water.

Completing the shoe upper is the BOA lace-up closure - a dial-in system that is able to resist water tension, so you don't have to worry about your laces getting untied while you swim or waddle through streams or rivers. There's a plush foam collar for maximum heel comfort and the Charged Cushioning in the system that absorbs impact and converts it into a responsive burst of power.
