Beautiful boots, smooth grain leather

Thank you for an easy exchange process and the delivery and return was quick too! Beautiful and smooth leather boots, true to size, and Made in Australia! I didn’t experience problems and pain because it’s new. Thank you for the freebie too! All the best!

Brilliant boots - Comfy/Really lightweight, proper leather

So far so good, I've had these for over a month now and have near enough worn them everyday. Just got back from a 3 week trip in the alps and they've gone from Mountain paths to restaurants. They are really lightweight, comparable to wearing trainers and have a soft/air filled sole which make them really comfortable.The leather is decent quality too, doesn't scuff really easy like some boots do and isn't stiff like cheap steel toe boots

Comfy and duel purpose

I wear these boots to work in London and on the farms when I visit my brother up north. The dirt or mud just wipes off and is super easy to clean. Very comfortable and order half size so just spoke to Ryan and he sorted me the right size. Excellent customer service. Can't recommend after years of other boots, I'll wear these over my Bluntstones

Excellent boots
30 January 2024

This is my second purchase from big boots and once again I am really happy. Brought these boots for day to day use, they are very comfortable and look great.

Great fit!
25 July 2023

LOVE these boots. The sole is so springy and comfy - I chuck them on when I’m waking the dog, gardening or heading out the door. A beautiful design that I think looks more expensive than they are! Good fit. Recommend.

Great product and supplier!
2 October 2024

Love the new boots! Very comfy and look great, perfect for the changing weather into Autumn.Would reiterate to buy at least a size smaller than you normally would; I'm usually a 10.5 but ordered a 9.5 and they're still not tight (perfect with chunky socks).BIG Boots UK were great at dealing with a return item I had, very efficient and friendly, would definitely recommend!

Great service, great boots
23 September 2024

Ordered the size down, but found them a little tight around the mid foot so exchanged for my usual size. Ryan was really good to deal with for the exchange.The boots are awesome, look much slimmer compared to a pair of Redbacks, a really solid work boot but without the bulk so I can still wear them to the office. Insole is extremely comfortable compared to other similar boots I've tried. Highly recommended.

Love my Mongrel Boots!

I was so impressed by the service and knowledge from Melissa and Adam (?) at the Burleigh store. They were able to help me to get the comfiest work boots and I havent stopped wearing them!

I used to only buy timberlands but these boots are so much more comfortable and easier to put on and off. Easy to clean and go with all my outfits. Use it for work and for weekend walks.

The most comfortable boot that goes with everything
27 September 2023

These are honestly the most comfortable boots - the insoles in them are a game changer. They’re smart leather boots that clean up really well, which mean I can wear them out for dinner and in the fields! I have the black and the dark brown colour to go with everything.
