There are 3 main ways to prevent blisters on your feet. I will
divide them into the expensive ways and the cheap ways.
1) Use tape:
Expensive: Buy moleskin or any form of 2nd skin type of tapes.
Failing which, use leukoplast.
Cheap: Use black tape. Quite good.
2) Good socks:
Expensive: Fox River from Campers Corner near City Hall. Wigwam
from military shops such as Sheares Technologies on Selegie Road.
Thorlos from World of Sports. These socks have good moisture
wicking ability and are damn damn comfortable. I've never gotten
any abrasions or blisters with these pairs no matter how far the
marches were.
Cheap: Buy any nice, thick pair of socks that are synthetic.
Cotton and other natural fibres are NO NO. Don't be fooled by what
the beach road ppl tell you.
3) Good boots:
Expensive: Get a pair of Black Hawks from Sheares. ($300
lol)
Cheap: Get Goretex, or just use a pair of very well-seasoned
rubber boots.
For abrasions on other parts:
Groin: Use tights, or don't wear anything
Anywhere else: Use black tape, leukoplast or moleskin to patch
up the hurting areas.
Hope this helps.
