Hiking shoes
Outsole: Featuring a durable, anti-slip outsole, the Hydro Moc makes the ideal footwear for water hiking in the summer. Its sole features a less aggressive oval lug pattern with 2mm depth. Shallow lug patterns are great for hard and smooth surfaces, such as rocks, pavements, and concrete. However, they may not work well in soft terrains, such as mud, grass, and loose dirt.
Midsole
This water hiking shoe has a midsole made of EVA - a foam-like material that is durable and flexible. Another notable characteristic of Merrell Hydro is its lightness. Unlike other types of shoe cushioning materials, EVA is much more lightweight. It's also touted for its high bounce rate and shock-absorbing qualities.
