I was going to post all about trainers, but now see it is "boots only". I don't have boots and have only ever worn trainers, now cheap ones (More Mile Cheviots at £19.99) which are fine for my old feet - just finished my last section of Cambrain Way in them.
I think it is what you are used to, find something that fits and then stick to them and train in them, there is no holy grail other than wear them and walk in them. The more you train the better they become....hopefully!
I work at Alpkit - The only reason they don't say 500g gas canister is the EN test does not specifically state it has been tested on that size. You will find that on a range of stoves, a large amount of stoves also recommend using their own brand gas canister for the same reason as they were tested on those only.
From experience using any size gas canister is fine,

I've just had a trial screwing them on a canister. Interestingly the Koro stove does not work with the Coleman 500 canister, it doesn't quite screw on far enough to engage and let the gas out. I tried it with 3 different Coleman canisters, 2 x brand new and unused and the other half used. It does engage with the 250 and 100 canisters, I guess there is some tiny difference in canister manufacture - but is a bit of a pain!
My Krakau stove worked with them all. I have to say that both stoves are very tight screwing them down before the gas is released, I read you should be able to put a piece of paper between the stove and canister rim, but a very thin piece of paper at best!
Many thanks for that Jay, I only want to use the free standing Koro with the 500gr, as I go fishing and camp in the back of the car for a few nights - the bigger canister is more economical for cooking. I shall give it a go hoping I don't blow myself up!
Nice stoves by the way, the little Kraku does the job for my trekking, I bought it to replace my old Pocket Rocket which gave up the ghost after many years abuse. A good combination of stoves to cover all my needs.
Also purchased the wind shield - what an improvement from me chasing bits of old aluminium across the hills as my homemade ones blew away!!!
I've recently purchased both the Koro and Kraku stoves from Alpkit, both do what I want.
But one question is, they both say on the instructions "for use with 100 & 230gram LPG canisters certified to EN417". Anyone know why they cannot be used with the larger 500gr (which I like to carry in the car for fishing use and is cheaper gas), I use mainly Coleman canisters and the 500gr also meets EN417.
