Superb protection from the elements with a high level of breathability, keeping your feet dry and comfortable from the first step to the last.

GORE-TEX® TechnologiesIf you predict unpredictability on your backpacking or hiking trips, then the Mammut Ayako High GTX will be the ideal boot for you, allowing for any eventuality.

Providing you with the lasting memory foam comfort, waterproofing and breathability that you need for anything from minor temperature fluctuations to freak downfalls, they'll ensure that you’re never caught short.

It has a GORE-TEX® construction to the lining and tongue, while the Vibram® Mulaz outsole, with its integrated Climbing Zone, provides you with a firm footing and great traction across various terrains and Via Ferrata.

Their external TPU Motion Control uses a reinforced interior to prevent the foot from twisting outwards, and their FeetMap System ensures that all the relevant cushioning, warming and non-slip lining materials are located in exactly the right places.

Women's Footwear Size Guide

Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet.

Many people have feet of different sizes. Fit to the larger of the two.

Remember, feet can expand over a quarter size during a full day's walk so ensure you get the right fit.

Superb boots

Bought these boots last summer as my old boots were actually hand me downs. The first thing that attracted me was the colour if I’m completely honest but after trying them on in the shop I immediately felt the support around my ankles. I am notorious for going over on my ankles and countless times I’ve limped down mountains and hills due to minor sprain injuries. First outing in these boots was my first ever time up Ben Nevis, they were an absolute dream, no ankle sprains, no rubbing or blisters and even kept my feet dry during a down pour on the descent, worth every penny!

Mamut boots

I bought these for my daughter her primary decision was she liked the colour. I have no idea if they will be used properly but since I own an SUV and have never driven it off road I don’t think I’m the right person to comment.

Great ankle support, so pleased

Thanks to those who have already left reviews about how good these were for ankle support! I went into the store to try these as I broke my ankle last year and have had lots of problems with pain and discomfort. These boots were amazing. Like one of the other reviewers I also walked in Scotland without having a chance to break them in. My feet stayed warm, dry and supported all day and no blisters. I am thrilled with them and super grateful for all the help the GoOutdoors team gave me on the day - we had an amazing trip and can't wait to wear my boots adventuring again.

Unfortunately I am extremely disappointed with my boots!
Yes they are super comfy and haven’t rubbed at all!
However I have worn these boots twice my feet have been wet both times and I have had zero grip as the ground has been wet! I treated the boots with recommended product before use! I feel I have wasted my money!

A Great Boot

My husband and i recently got caught in blizzard conditions at -8 and -19 windchill in 4ft of snow and were forced to camp out an extra night on the hill .This was the first time i had worn these boots and we were on our feet for HOURS in harsh conditions . They were superb and kept my feet warm and dry even after a quick dunking in a freezing stream.A stiff sole at first but once accustomed to this they are extremely comfortable leaving me with no hot spots and non achey feet afterwards.If you would like to see them in action the vid is on a very popular video channel under 2 feet forward.

Excellent product.

I bought these boots the day before travelling to north Scotland, so didn't have time to wear them in - no problem though! These boots were very comfortable from the off. Having worn them in temperatures of -12 they kept my feet warm (no mean feat as I suffer in cold conditions). They have not rubbed anywhere - thanks in part to the three levels of lace control and the memory foam padding. Great when icy underfoot - traction was excellent. I haven't worn them in very wet conditions yet, but I did treat them before first wearing with a recommended product, so have every confidence that my feet will remain dry. And being a woman...I have to say...they look great too! Great buy.

Great boots

After getting back into hill and mountain walking following a foot and ankle injury, these boots are beyond perfect. The memory foam ankle support has ensured that I summit-ed Ben Nevis no problem! These boots offer great support, keep your feet cool or warm and are really comfortable to wear. They are also not too heavy. I highly recommend.

Mammut Ayako High GTX

These are superb boots. Warm, lightweight, comfortable, fully waterproof and sturdy. Took me up and down Ben Lomond on their first outing. I’m a fair weather hiker but these saw me through an autumn day of non stop rain. The additional ankle support design helped me as I have twisted both of my ankles several times over the years and was able to hike over path, rocks and mud without worrying I was going to go over. They are worth the problem ex tag and in fact I think I got more than I paid for. Helen

Sturdy and supportive while still light. Brilliant support for fallen arches.
