Men's toe nails curving under from the sides, big toe and little toe?!

Men's toe nails curving under from the sides, big toe and little toe?

Causing the tissue under the nail to be trapped between the nail's curvature.

The big and little toes on both feet are the affected ones.
I wear loose fitting, wide shoes.
In my adult years, I have put on some extra weight, could be a contributing factor. 5'6" 180 lbs.

I don't think age is a factor, although I am 60 going on 29.
If anyone could help before this becomes a health issue I would appreciate it.
My last visit to the poditrist(foot doc) when unnoticed/responsive.

I had a ruptured ligiment at the end of my index toe, I guess that would describe the toe next to the big toe.
All my life I have been very athletic, even now I continue to be very active. Am I wearing my feet out?

I've had this problem to some degree, too. The best thing I did was change to a better, well made, well fitting shoe. While you're on the right track w/wide shoes, the loose fit may aggravate the problem. Your foot may be shifting forward putting pressure on the toes without you being aware of the change. Very few retailers measure feet properly, probably because few offer shoes in the range of widths to fit anyone out of the norm or majority.
I had the problem worse on my right foot when I drove my old Mercedes diesel an average of 400-600 miles a day-the accellerator spring was verrry...uber strong, very teutonic. I seemed to push with my toes I guess.
Age may be a factor-I'm 50 going on 29,myself-on my feet a lot. But I remember as a very small child my dad, he would have been in his mid 20's, having the problem so bad that he would cut the toe area out of some of his shoes to wear when he could be discrete.
The advise I've always tried to follow is to trim the nail closer at the mid-point than in the corners, & trim often. Also try using a file or emory board to flatten or thin the top of the entire nail surface-theory being growth will be directed to the thin area. Of course this applies to the big toe, but do what you can to the little piggy.
If you are diabetic like me, don't delay acting-if something doesn't help soon, find a better foot doc-maybe get a ref. from your primary doc. Whatever you do don't ignore the situation. Also beware the dreaded fungus problem-yellowish & thickening nails. There are cures,but they can be expensive.
I'd be glad to share some specific shoe brands but I'm not sure of the rules here. The best I've found are S.A.S shoes,(San Antonio Shoes), still made only there & sold only in their factory owned stores all over Texas, but maybe other states now, too. They made their rep.selling shoes for and to nurses...who along with waiters/waitresses, beat cops & corrections officers like me live...or die on their feet .
