Try telling a drill instructor at Infantry Training School that you can't go on training because your feet hurt. It took me about 2 weeks of constant humping up & down hills at Camp Pendleton before my feet were tough enough to avoid blisters.

>>>What did you buy;an AMK light and fast Trail or Adventurer?

It's the Trail model. Nice basic kit for day hiking. They packaged it in a convenient format. It has room to allow you to augment it with additional supplies for your needs.

I also like their Ultralight kits, for backpacking, with the waterproof inner bags, but, this Fast and Light format is more convenient to get what you need out of the zippered compartments. (It's not waterproof, so I have my son keep it in a ziplock freezer bag.)

Here's a sure-fire, though unconventional, way to prevent blisters: go barefoot.

Obviously this only work in relatively warm weather, and on most trails you'll go a bit slower barefoot, but it's the healthiest and most comfortable way to go, and you'll never get a blister this way. Although I'll admit some really rocky trails can be painful, others are a real pleasure. It also takes a little time for your feet to toughen up, and for most people it takes a bit longer for the foot and ankle muscles to develop.
