Heading out to explore Auckland

Last night we met up with Jon and Charlie and had a great steak dinner. We got the best night's sleep in several nights and feel great. Today we're meeting up with some friends of theirs from SFO and we've hired a guide to take us around Auckland. I'm hoping to get some new walking shoes or boots. I brought a pair of sneakers with me that are identical to the ones I wear to work out (just newer) but apparently something is different - the right one is really painful to wear. Fortunately I have other shoes, but none really good for long walking. I'm thinking I will look at hiking boots - which they call "tramping boots" here.
