Going on holiday next month to a hot country. It'll be just under 30 degrees and we'll be doing a bit of hiking. It's the rainy season and I have Goretex walking shoes but they can get a bit sweaty in the heat. Can anyone recommend a good pair of walking boots that would be suitable, and are also reasonably stylish? I'm thinking a mid-rise brown (leather?) would be good? Women's shoe size 4. Thanks!
