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.

Men'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.

Good for hills, bad for anything else

This is a superbly comfortable 'out the box' boot. Easily adjustable and waterproofing has coped well. However the Vibram sole unit gets destroyed in rapid time if you have to walk on tarmac.

Pro's & Con's

Pro's - They are comfortable, hard wearing, good edges for scrambling, high rand for scree.
Con's - whilst still plenty of tread, soles coming unstuck, stitching disintegrating, no longer waterproof.

Excellent boots but one gripe

I got these boots from the Chesterfield store and they were ready to go straight out of the box.

They are extremely comfortable but the sole is wearing out much quicker than I would like.

For Mammut relay disappointed....

Considering the cost relay disappointed with these boats. After returning from a hillwalk the rubber toe guard had split and started to peel away (just behind the Mammut badge). Really bad design

Good solid boot

Good solid boot, have had a long history of wearing Mammut boots and have always been impressed. These fit well and seem too have stood up to everything so far.

Awesome boot giving all day comfort. I’m on my third pair. The only slight downside for me is that the sole is slightly numb compared to the old style but that’s just my personal preference

Great boot out of the box

After plenty of research online I decided to go for the Mammuk Ayako to replace my 14 year old Scarpa boots. I tried these on in the store and instantly knew these were the boots for me. A nice fitting for my wider than average feet, a great lacing system which really held nicely to give plenty of ankle support. I took these out the following day for an overnight in the forest and have not had any issues yet.

Fanstastic boot straight out of box.

Bought these the day before climbing Snowdon. Not even put my foot in them, until I was at the car park ready for the Pyg track. Not one complaint comfy, sturdy, an overall great boot with fantastic grip. Would like to say thank you do Go Outdoors, their staff give you sound advice, and are always friendly. Highly recommend.

Great boot for the summer

I bought this boot to climb Mount Toubkal. The fit was great, very comfy out of the box. I was trekking for 3 days solid between 6 and 15 hours and not 1 blister or foot fatigue! Boot give great protection against the rocks and the grip is also great.

Downfall to this boot - it's not waterproof. I walked through a few shallow streams in the UK and my feet became wet almost straight away but, if you are looking for a boot for summer trekking only, this is a great option. If you're looking for an all rounder to use in wet weather too, I'd suggest looking elsewhere.

Strong set of boots

These are by far the best boots I’ve purchased. Comfortable, lightweight and very hard wearing. The water resistance is also second to none. Would definitely recommend to anybody who loves Hill /mountain walking.

Fantastic boots! After spending forever trying to find the right ones I eventually chose these after being advised by a very helpful member of staff at the Wolverhampton branch. They are very comfortable, fully waterproof and the ankle support is fantastic....fully recommended

Wonderfully comfortable boot

Personally I love how supportive and stable the boot feels on all sorts of different terrain. They feel strong and very well made so I’m fairly confident that they will last the test of time and yet despite this they’re still light on the foot.

Very comfortable and grippy in all weather and terrain

Purchased roughly early July, thought I’d give them a good bit of use before reviewing. Wore them over different terrain, in different weather and for different purposes. Excellent for snowdon toward end of summer, very comfortable and breathable. Also used them over approx 20 miles in Snowdonia but on mainly tarmac with the odd gravel track and again, very comfortable. I used them in the Lake District in autumn and winter and can’t fault them, excellent grip when needed, comfortable and although not what I’d class as a high boot coming from wearing lowa military boots, they seem to offer the same ankle support and water protection when crossing streams etc. Also had a lot of use in the Peak District in all weather and again, I really can’t fault them. Warm when needed, cool when needed and excellent comfort and grip!

Superb boots

I could not decide between three pairs of boots and initially thought the sole of these was a bit hard however Im so glad I chose these in the end. Lightweight, comfortable, waterproof and sturdy. Great value for money.
