What are the common problems we get on our feet while climbing mountains?

Climbing mountains puts a lot of strain on the feet and a combination of pressure, moisture and continuous friction caused by socks and hiking boots lead to the formation of blisters on the feet of mountaineers. Blisters are a common occurrence on mountaineers' feet. And as we can see in the chapter Sangeeta madam was no exception. But since blisters are almost an integral part of mountain climbers' life, they cannot be a valid reason to stop trekking.
