Like others have said have you tried a foam roller? Or try freezing a small bottle of water and use that as a roller. You'll get the benefits of rolling and icing in one go. I'd also look at your warm-up and cool down routine. Do you do any specific exercises for warming up the calfs and shins. I do a lot of walking on my tip toes and heels. I also do some backward walking at the end of runs which seems to help the calfs too.
I ran my first half marathon a couple of weeks ago and since then I've felt demotivated. After a few days off I've managed three runs and a couple of light cross training sessions at the gym. After my last run of just over 3.5 miles it was a struggle to be bothered with the cool down and stretching.
How long would you expect a pair of Thorlo Experia socks to last? I bought a pair at the beginning of July this year and have done just over 200 miles in them. They seem to be wearing thin at the bottom (the part were the arch of the foot is.)
