Shoe? Sandal? Land? Water? Merrell® Hydrotrekker Leather Sieve Shandals check all of the above. Leather uppers are not only stylish but water-friendly. Speaking of water, the M Select WET GRIP outsole is siped for traction on wet surfaces. It's also durable to trek over land and rock. And should your adventures lead to lake, river, or sea, the Hydramorph midsole releases water so you don't get bogged down. For hiking, tubing, fishing or just exploring, these are an ideal choice.
