Questions & Answers

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.

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 The Best walking shoe ever!! I brought these upon recommendation from the Mackay store for work. I work in security, my shifts are 12hours. They are light weight, supportive, and have less impact on my old knee injuries. Love them!

Rated 5 out of 5 by from Merrell siren I purchased the shoes two weeks ago without any research on them. I tried them on in store and purchased straight away. Best boots I’ve ever owned. No pain in my feet, they are wide enough around the top of my feet nil pressure. No sore feet when I wake in the morning. These are my work shoes and in them every day! I will be staying with this style of shoe as long as possible. Love them

Rated 5 out of 5 by from Tough, durable, comfortable Wearing them almost every day. Good for wearing to work, at home, in garden

Rated 5 out of 5 by from Very light and comfortable These were brought for deer stalking as I needed something light, flexible, water resistant and with good tread. Also having the high tops allowed the gators to cover the shoe well. They fitted the criteria perfectly and were very comfortable. No rubbing or pressure point after wearing them for a few hours on the first day.

Rated 5 out of 5 by from The best investment! I bought for my recent overseas trip and can honestly say it was one of the best investment!! They held my feet very well and without fail, kept my feet dry and comfy throughout the trip. Dirt can also be wiped out easily. Cannot recommend this one enough.
