Rated 2 out of 5 by from Look great but not comfortable I was a loyal Merrell customer for years and always considered their hiking shoes among the best on the market. Unfortunately, I have to say that I regret purchasing Merrell Siren 3 Mid GTX Women’s Hiking Shoes. The shoes look really great and if you do not walk far they feel ok, but with the number of changes Merrell did to their Siren model in past years rendered them useless for me. I have wide feet but all Merrell Siren shoes on the market in recent years designed for narrow-footed Cinderellas. Over the last 4-5 years, I could not even stick my foot into their new Siren models shoes so narrow they were. Siren 3 Mid GTX felt ok when I tried them in the shop and later when I started wearing them at home before the trip. But they are not leather and they turned out to be very rigid. Unlike al previous Siren shoes I had these ones refused to “settle” into my feet shape but rather tried to “molt” my feet into theirs. They also are not “breathable”. After hikes of no more than 5km my socks were completely wet even although I was wearing hiking Merrell socks. Long hikes I finished half-blinded with pain. I wish Merrell returned to their old models when hiking shoes were great: light, breathable, leather, fit for wide feet; high ankle support & suitable for a subtropical and tropical climate that is a huge part of Australia. Until then I will have to start looking somewhere else for good comfortable hiking shoes and will try to forget ruined holiday

Rated 5 out of 5 by from Very comfortable I find these shoes very comfortable and with good support. I wear them everywhere not just for hiking.

Rated 5 out of 5 by from All day comfort I bought these boots recently. Whilst I don’t use these for hiking, I wear them to work where I am on my feet all day and do quite a lot of walking, they are very comfortable. I wear these with an orthotic and they offer the stability I require and my physio and podiatrist both gave them the thumbs up.

Rated 5 out of 5 by from Comfortable I’m happy to buy this shoes, very comfortable, light and looks good on my small feet.

Hi I am looking for new lightweight training shoe I have quite wide feet would this boot be ok or would I be better to go with a men’s fit?  If so I am a women’s 39 what size would the men’s equivalent. Thanks 

Asked by: Kathryns
For your size foot womens shoes/boots will be the only option as mens sizes seldom start that small. Merrell are on the wider end of the foot shape continuum, you could also look at Keen as another brand with a wider fit shape.

Why does your sizing guide for this shoe refer to clothing measurements and not foot measurements?

Asked by: HelenK
Apologies this is of course an error. It will soon be updated by our Online team. In the meantime please refer to the sizing guide in one of our other listings.
