Given your £100 budget my advice would be for you to go to your local Go Outdoors and have a look at the Scarpa Delta GTX Activ Men's Walking Boots @ £198 https://www.gooutdoors.co.uk/scarpa-delta-gtx-activ-walking-boots-p20555 If they fit/suit your feet get Go Outdoors to price match here https://www.snowandrock.com/p/scarpa-men-s-delta-gore-tex-active-B1122414.html which should reduce the price down to £108.That's only slightly over your £100 budget but there really is a world of difference between the build quality of the Scarpa boots and that of the Hi-Gear boots. I'm sure you will find it's £8 well spent.

The price at Snow & Rock hasn't gone up and has been £120 for a while. If and when you ask for a price match in store at Go Outdoors they should beat Snow & Rock's £120 price by 10% (£12) which gets the price down to £108. https://www.gooutdoors.co.uk/price-guarantee
