Not surprisingly my thoughts are slightly different. What possessed you to choose an Arc'Teryx boot because they're not exactly well known for their boots are they? They are far better known for their clothing range and their marketing department is highly skilled at fleecing gullible customers with more money than sense into paying extortionate prices for the Arc'Teryx "brand" name.
If your main priority is to have waterproof boots which will stay waterproof don't buy fabric boots. If you want boots which will last more than 6 months to 2 years and want boots which can be resoled if and when required don't buy fabric boots.
My advice would be for you to buy full leather boots which will remain waterproof even when the waterproof liners have failed (and they all do) provided they are regularly cleaned and maintained they should last 5+ years and combine these with the use of good quality Gore-Tex or eVent walking gaiters in wet conditions. The price for this longevity is the added weight due to the better quality, longer lasting materials used in their manufacture.
Personally unless you want to be continually going back to the retailer seeking replacements I would avoid Salomon boots at all costs as they have an atrocious record for leaking after a very short period of time. Perhaps sussamb's boots are the exception to the rule but you will find many tales of woe regarding leaking Solomon boots on every walking related forum you visit.
I would also be very cautious about buying Meindl these days without doing a great deal of research for recent independant reviews. From what I've seen Meindl are not the bombproof option they were not that long ago. I believe they have slightly changed the sole composition/manufacture recently and are developing a reputation for the heels/soles being very fast wearing.
I would suggest that you consider adding the following Altberg boots to your shortlist of possible options
2-3 Season BootsAltberg Fremington Men's 1412g RRP £184.99 (standard last with 5 width fittings)
https://www.altberg.co.uk/boots/5-width-fitting-boots/fremington-menAltberg Malham Men's 1344g RRP £189.99 (A-Forme last with 1 medium width fitting)
https://www.altberg.co.uk/boots/aforme-boots13/malham3 Season BootsAltberg Tethera Men's 1472g RRP £229.99 (standard last with 5 width fittings)
https://www.altberg.co.uk/boots/5-width-fitting-boots/tethera-menAltberg Nordkapp Unisex 1460g RRP £234.99 (A-Forme last with 1 medium width fitting)
https://www.altberg.co.uk/boots/aforme-boots13/nordkappAltberg's standard last is available in 5 width fittings from Extra Narrow to Extra Wide. If the model of a boot made on the standard last doesn't quite fit or suit your particular foot shape, width and volume it's a fairly safe be that a boot made on the A-Forme or G-Fit lasts will. All Altberg boots can be resoled if and when the need arises wheras most fabric/leather combination boots cannot be resoled due to the way they are constructed.
The cheapest place to buy Altberg boots online is usually Taunton Leisure
https://www.tauntonleisure.com/altberg/boots although I would strongly recommend that you should visit a retailer to get properly measured and try before you buy. You can find your nearest stockists here
https://www.altberg.co.uk/stockistsGiven your location The Outdoor Shop, High Street, Llanberis, LL55 4SU may be worth a visit when Covid restrictions are lifted. They should at least be able to measure your feet using Altberg's own measuring system although not being an Altberg Premier Retailer they may not have a wide range of Altberg boots for you to try on. If that's the case they may be able to order specific models and sizes of Altberg boots in for you to try or you will unfortunately have to travel further afield.
