Why We Like The Merrell Siren 4 Mid GTX Hiking Boot
Backpacking trips take us across diverse trail conditions which is why we depend on the Merrell Siren 4 Mid GTX Hiking Boot to keep our feet happy throughout the journey. Equipped with a rubber toe cap and an integrated midsole plate, this pair protects our feet from bruising on rocky trails, while the gusseted tongue stops debris from wriggling in and wreaking havoc. With a water-blocking GORE-TEX membrane and a sweat-wicking recycled mesh lining on their side, our feet stay dry through stream crossings and lung-burning climbs.

Defective waterproofing
I loved these boots initially. The fit is comfortable, and the high top ankle support is soft and very comfortable. Colors are great. I took them to Iceland and by 3 days of light hiking use, noticed the gore-tex outer coating crackling at the stitched edges. That would be my one major complaint, as the waterproofing is now immediately compromised and gore-tex is always an added cost.

Merrell for the waterproof win!
Comfortable from the first wear. Warm and waterproof but not too hot. I love that Merrells consistently have a slightly wider toe box without a wide heel. If you're feet are slightly duck-foot shaped (like mine) cannot recommend highly enough! Consistently a good fit, durable, and comfortable.

Fantastic boots
Love these boots because they fit well, are well made, were comfortable right out of the box, didn't overheat my feet, and provided plenty of support when I took them on their first adventure to Bandelier in New Mexico.

Winter Walking with ease
I walk every day between 3 and 5 miles, very often on snow covered roads. I got these specifically for those days and I have been very happy with how they perform. The Vibram soles give me so much confidence on slippery surfaces. The gortex keeps my feet warm and dry. Thank you Merrell!!!

New hiking boots
Preparing for a trip to Utah and a 6 day hiking trip. Got my hiking boots and walking the lake trail and woods near my home. Shoes are super comfortable right out of the box. Feel like tennis shoes but support my ankles. I fractured my right ankle a year ago. I thoroughly recommend these shoes.

A little narrow
I haven't tested them in wet conditions, but as for sizing, they are just a bit narrow. I've worn Siren 2's and 3's for years, one of which is the waterproof version. I think that the WP versions simply don't stretch out as fast as the non-WP versions do. I bought the same size as the other Sirens (after trying 1/2 size up too - it was too long), but I doubt I'll ever be able to wear thicker shocks with this boot. Otherwise this is a nice, lightweight boot that has some arch support, although I always add my own insert. I am feeling something rubbing just a bit around the inside ankle, but it hasn't bothered me too much yet.
