For skate style shoes I'm a fan of Nike SB and Lakai. Anything over about $70 will generally last. My Nike Shane Premiums have walked all over Europe and are still in great condition.
I also recommend Vessi. They're waterproof, breathable, comfortable, and my wife and I wore them in all sorts of rough use cases and they are still going strong years later.
It's generally very safe there, so not much to worry about. If you are planning on doing a lot of hiking in unpopulated areas make sure you do your due diligence. The weather is pretty nice in the summer. Nearly everyone speaks good English, with the exceptions of some older people and those in rural areas. Enjoy your time there, the people are friendly and the land is breathtaking.
