SoxyMens Black Colour Heel and Toe Socks - 12 Pack - Comfortable, Everyday, Cotton Rich Breathable Socks - Mens UK Shoe Size 6-11

Quite tempted to purchase these...could I be reassured that these won't develop wholes within a few months...as the last pack of sox I purchased were.

Can these socks be washed and dryed in the machine? Thanks for your answer
