Footwear & footcare

Currently using: Asics Trabuco GTX 12
Go to shoe since 2017 and no blisters yet. Light as trainers but with excellent cushioning and grip. No need to walk them in, but I manage to walk the out in about three months before replacing them. Waterproof enough to walk through streams. Ventilated enough to walk in the Spanish sun. The latest model, 13, did not work for me, so currently buying old stock and hoping that the next model returns to form.
As with all walking shoes, I buy them a size bigger than my usual shoe size, to allow for feet swelling. I find they last me about three months of solid walking days before they need to be replaced. Older models can be found at lower prices on line. My current pair, £75 new from http://www.sportshoes.com
For socks, wearing two pairs of lightweight Decathlon hiking socks has always worked for me. For the latest walk, I invested in a pair of Wright Socks double-layered walking socks, and so far I’m impressed, although they do take a little longer to dry.
As for footcare, I try to keep feet dry at all times, and apply a generous amount of vaseline every morning. So far, along with sizing up shoes, this has worked for me and I have walked for years blister-free.
Rucksacks

Currently using: Osprey Exos 38l
I have been using an Osprey Exos 38l since I started walking multi-day hikes, and I love it. If I consider other models, it is always with the specs and features of this model in mind. I’d like to try the Eja women’s model, but they are harder to find in shops and rarely in the sales, probably due to women being quite rare.
Weight distribution through the substantial hip straps makes even heavy loads manageable. I try to keep to under 10kg including food and water, or slightly over if carrying a tent.
The breathable back system makes it comfortable to use in hot weather, but you do need to buy a waterproof cover for rainy days, as this is not included.
Another favourite feature is the stretchy back pocket, which is super handy for storing half-dry socks, snacks, sunhats and the like.
Walking poles

Currently using: Crivit alumininium walking poles
For years, I didn’t understand why these were necessary. Now I would never do a multi-day hike without them.
Weight is spread more evenly, taking a lot of the strain from the knees and reducing the risk of tendinitis.
Hills are easier. Going up, your arms do half the work, going down, knees are protected and stability maintained.
On the flat, if used in a nordic walking style, you can propel yourself along and keep going for longer if you need to.
They are good for waving at dogs and knocking down fruit.
They keep my tent up.
Model unimportant, as long as they are adjustable and have comfortable hand slings. Mine are Crivit from the middle of Lidl and they do just fine.
