training (back from injury)

Hi all
Where to start, well after talking to other runners/ friends that run I've decided to change the shoes, but which to go for theres so many and I'm 98% sure I'm a neutral runner. The shoes I've had so far are New Balance which are off road and road but more suited to off and saucony which are road. The New Balance I've never had a problem with even with higher mile runs and the saucony I've had both the Achilles injuries and after so many miles i seem to start to ache. Today i went to buy some new shoes tried multiple brands which i didn't feel right in so tried a few pairs of New Balance on and they all seemed so good so bought the ones at the max end of my budget, haven't tried them yet but sure they will be great. I did my 5k on Saturday which went OK, then Saturday evening did some strength training, had a total rest day Sunday. Today was shockingly bad weather but went out for a five mile run none the less and got absolutely soaked but was like a little child in the puddles glad i didn't go out in my new shoes, in fact i enjoyed it so much I'm getting the off road shoes out tomorrow and going for a mud run will let you know how it goes.
