I wear these for Racqetball.

When they first arrived, I thought that they were so very thick that I wouldn't fit in my shoes with them on!  Turned out not to be a problem.  Sure, it is a bit snug, but not a problem.

So, when wearing these, it feels like my feet are surrounded by a protective cushion.  I bought them at the same time that I bought a new pair of shoes and started playing Racquetball for the first time in a long time.

I'm shocked that I've gotten no blisters or hotspots.  One might say that the shoes are good (they probably are), but I'm thinking that these great socks are protecting me from those prospective blisters/hotspots.

HOWEVER, yesterday I played for 3.5 hours.  I found that the cushioning kind of went away as the socks became saturated with sweat -- no problem -- I can just change socks every few hours when I'm having such marathon sessions.

Am VERY happy, overall, with these socks.
