So I started knitting these socks on the treadmill. I cast on and got the ribbing started, then I hopped on the treadmill and ribbed until I thought it looked like enough ribbing, and then switched to stockinette.
Session 2 was just knit knit knit - walk walk walk. I think I can get one more treadmill session in the ankle before I will start the heel.
I can't see myself making the heel flap and picking up stitches while walking on the tread mill, so I think after the next session I will have to knit the heel when I am couch surfing, and then when I get the heel done I can get a couple more sessions out of these on the treadmill before I make the toe.
Since I have to have the socks out of treadmill rotation while making heels and toes (at least until I become a sock knitting ninja), I think I will try and have a couple pairs of socks going so I will always have something I can work on while walking.
And yes - I have sweat dripping off my elbows while I am knitting. Because my arms are bent, the sweat never hits the socks or yarn. Satisfying to be knitting away and dripping sweat! And I walk longer because I am enjoying the knitting and not as focused on the time or the miles. I am not seeing a downside to this!
