Hiking Apparel

I think the hike about five miles. I have not traveled before.
I was wondering what to wear, carry and take.
will be the gym to be okey short in the heat of summer or do I have special clothes?
any recommendation is appreciated. thanks

If the land is flat sneakers is ok, if its rocky hiking boots get, you need a backpack, and pack: mobile phone in a waterproof bag, water, clothes, make a meal, are you yourself or a withsome, do you know the area, a few notes: 1 check the weather, 2 let someone know where and when you go

in the heat of summer you will be well with shorts and sporting a t-shirt ... the usual rule of thumb when hiking is that cotton kills if you pack fleece / polyester and a shell / windbreaker rain jacket ... but in the heat of summer, shorts and a t-shirt will be perfect for the most part, assuming you're not hiking in the higher elevations (Rockies, waterfalls, etc.) .. pack of water right and good shoes
