Merrell Moab Speed 2 Gtx Gray Men's Outdoor Shoes J00005347

Hello, yes, this Merrell model has Gore-Tex (GTX) technology, so the product is waterproof. It will effectively protect your foot in rainy and wet conditions. If you have any other questions, we will be happy to help.

Hello, for a foot size of 27.1 cm, size 43 in Merrell molds will be more suitable. Size 44 may be a little wide. I recommend you to choose size 43 for the comfort of the shoes. However, if you like a looser fit in the shoes you wear, you can also try size 44. You can also check the detailed measurements in the size chart on the product page. � �
