Flowerpower - yes, I'd say it's the socks. Make sure socks are smooth material and the right size, not loose. Also, don't wear cotton socks. Avoid running until it gets better.
Redalert - well done, you've gone so far on your own! First aim for 10km, first, not 10 miles, a bit easier
Do you mean you get bored on longer runs? I would recommend that you just do one longer run a week - this is a slow run so whatever your longest run at the moment, start adding 5 minutes or so to that each week (you can take a break some weeks and repeat what you did the previous week). Go really slowly on these runs and try to make it easy. Nice to do long runs at weekends, during day light and try different routes so you won't get bored. Then twice a week do your regular run, about 30mins and make one of these fast or do some intervals - look up tempo runs and/or fartleks - these are shorter but more demanding sessions. Your third run can be just straight forward 30mins at a comfortably fast pace or maybe with a friend or a club? Makes it so much easier when you run with someone else. I'd recommend cross training on other days, if you want to train more than 3x week so try to pilates, yoga, swimming, gym, spinning, cycling... find something else that you enjoy. Too much of the same thing will make you bored and is no good especially if you tend to get bored! I'm the same myself
Hope this helps x
