Ease and Durability of hand knit sock.

I knit my socks to fit.  That raises the question of how much negative ease to avoid the wads and creases that can cause blisters.

The thing is that too much negative ease causes socks to wear quickly.  Thus, negative ease should be minimal.  And, a firmly knit fabric requires much less minimum ease to avoid blisters.

Firmly knit fabric, knit to fit, works well for socks.

Then, put a clock on the ankle to make the sock easier to put on and take off.
