I have looked to see if this has been discussed before but was unable to find anything to relate to the specific type of blister i have been having, but apologies if this is repeating any previous threads.
I run frequently and last week completed my first marathon. After the race, i noticed i had blisters on the top of my toes. They are around the end of some of the toes but mainly on the top,and extend under the toenails. This has also happened to me before, a year or so ago, during a half marathon, but doesnt really seem to happen the rest of the time, even during long training runs. The trouble is, when i do get these blisters they put me off my feet for a looong time and make it painful even to walk.
I am wondering what causes them and how can they be prevented- i am sure it is not that my shoes are too small, as they fit well. I am also pretty sure it is not that my toes are slipping and hitting the end of the toebox, as i actually have a really large big toe compared to my other toes, and i dont get it on that toe- only on the 2nd and 3rd toe of each foot.
