Best Boots

Amazing boots, got them for my birthday recently. From looking for a pair myself, previously I was not sure, thought them too masculine. But no they are BRILLIANT, not clunky at all, and the lovely accent of the yellow laces makes them look great when I worn with jeans. They are waterproof and - big bonus - Very light weight, I would add this as a feature in the technical aspect of these boots, because I was pleasantly surprised about that and they don't need wearing in, they fit like a glove.
Considering to buy a second pair for when these are worn out but seems a bit over the top....

I really liked the boots but they were far too tight across the top of the foot but the length was fine which was why there no point going up a size. Very disappointed.

Excellent boots, very comfortable. No need to wear in as they are perfect as soon as you put them on.

Hello, Are the footbeds removable? I was hoping to replace it with my orthotic. Thanks!

Hello Ellen. Yes the footbeds can be removed from the shoe and replaced with a footbed of your choice. I hope this helps.

I have wide feet and need an extra width in the toe box area. What width fitting are these boots? Many thanks.

Hi Janet. Yes these boots are wider in the toe box area, Merrell are normally almost a centimetre wider than other brands. perfect for daily use or for trips out on the hill. If you have wider feet and are concerned about the fit why not visit you local Black's to try a pair on with one of our experts. Many Thanks.
