MADHOLLY20Pcs Breathable Gel Toe Cap, Prevent Callus and Blistering, Silicone Toe Protector for Women and Men, 16M + 4L

Are these toe protectors Breath-able? I need something to decrease toe pain all-day long; therefore,I don't want an added moisture or fungal problem.

I have man size 7.7 and need something to help my little toe from sock bunching and rubbing in work boots,. Will this work?

how long do they last? When would they likely break or need to be replaced if used per exercise/running session?

Will it fit women's size 9 4th toe (next to (pinky)?
