One of the reasons I avoid ankle carry is the fact that it is extra weight. I spend a lot of time on my feet walking. The last thing I want is extra weight on ankle. Also I have tendonitis in both knees. Extra weight added to my ankle means extra pain added to my knees.
Also it gets hot here for much of the year. I own twice as many pairs of shorts as I do jeans. My attire when not working when the weather is that nice also involves sandals. In this state we have two seasons. Summer, and winter. Some days you can experience both within the same hour.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
