I agree with everything posted! Keeping toenails trimmed is actually pretty important for serious runners. But, MORE IMPORTANTLY -- go to a shoe store that specializes in fitting people for running shoes. It sounds like you have what's commonly referred to (at least here) as "runner's toe" . . . it's from ill-fitting shoes. We have two shoe stores here that specifically fit you for the size, shape and type for the activity that you are pursuing.
One store, oddly, consistently fits shoes too small -- but then again the owner is a runner, likes his shoes short, and had his toenails removed on his big toes so that he wouldn't get exactly what you have! The other store, however, is owned by a woman whose father is a podiatrist . . . she is OBSESSIVE about the exact right shoe . . . I have been in there and had to try on 10-12 pair of shoes because she "just didn't like the fit" of the shoes! Each time I've been in there, though, I've come out with the best pair of shoes for what I need. Now that I'm in a wheelchair, and particularly given the way that I walk when I'm NOT, I am so thankful for her knowledge.
Each successive year, a particular "name" of a shoe, or a model may not have the same fit, last or qualities of the previous years. It's important that you get someone who knows what's going on with each type. Also, if you look for a store that is something like a "premium New Balance Dealer" (not necessarily a New Balance store), they are usually the type of store of which I'm speaking. In order to carry the higher-end, more responsive, more supportive shoes, New Balance mandates that they are these types of stores.
Good luck . . . and don't be surprised if you lose those toenails . . . if they're not damaged far back at the matrix, they'll grow back in. If they start separating from the nail bed and DON'T grow back in correctly, consult a podiatrist ASAP.
Yep buying running shoes is a crap shoot.
I agree with everything here although I have found that out of the real running shoes some makes are consistently closer to the shape of your foot. Obviously decent makes like NB also come in width fittings as well.
I have a very high arch which doesn't help so if I buy the wrong shoe the "comfortable" size on my arch is often too large so I slip and end up with my toes taking the beating.
However you can also buy inserts which modify the shoeliner. (the sponge part that comes out in decent shoes) ... this might help out for a few bucks if you have already invested in expensive shoes.
Really severe cases you can even get custom made sorbothane (sp) inserts which replace the ones in the shoe... These are expensive and you need to see a specialist to get them because they are made for your feet...
However if you do they are transferable from running shoes to tennis shoes etc.
Im just really mentioning this if you have already invested in good running shoes.
A really good running shop will be able to help.... it doesn't need to be the one where you bought them and for people on a budget a good trick is to get fitted in an expensive place and buy exactly the same shoe somewhere cheaper.
If you can afford it then a second different pair of shoes is nice... and alternate the shoes..... in reality its not more expensive since they will last twice as long... if you live in a rainy/muddy place probably more than twice as long...if you take care and wash them off after and let them dry naturally. Either way if you run regularly its nice putting on dry shoes, even if you are going out to run in the rain!
