Time for new shoes/boots?

[JustADude]

I've had the Asolo Fugitive for about 1.5 yrs and 400+ miles. I love them. Uniform tread wear on the sole down to where I can start to see the top of Abraham Lincoln's head.

These shoes have been super supportive and haven't gotten too many blisters, etc.

Given all the discussion about PF, when should I begin to get concerned about the midsole breaking down and the arch support/footbed support starting to deminish?

I would like to be pro-active before any PF type stuff even starts, so thanks for any suggestions about when to consider new shoes/boots.

Thanks.

A good shoe's midsole should last til the tread is gone. My experience.:sun

Cool. Thanks for the feedback. Just wanted to proactively try to prevent any foot injury.

Thanks again.
