soles for Altra Lone Peak?

Perhaps the Lone Peaks are not for you? Have a look at Andrew Skurka’s preview of the Salomon Odyssey Triple Crown – https://andrewskurka.com/2018/preview-salomon-odyssey-triple-crown/

More to the point of your question though, when I inquired about replacement insoles for Altras at my local REI, the shoe salesman highly recommended Sof Soles (Athlete model) with the warning that they were not zero drop and that they made the shoe fit tighter. I haven’t tried them, but I may when my Lone Peak inserts pack out.

I’ve used both Spenco hiker insoles and Superfeet insoles.  Both add some arch support and I think make them feel narrower.  The heels on the 4.0 feel a bit narrower to begin with, if that helps.

That’s kind of ironic that you’d want to put different soles on Altras. That’s how the company started. They were heating up shoes in a toaster oven, cutting down the midsole to flatten them out and then glueing them back on.

La Sportiva makes a narrower shoe but the toebox is narrow too. I’d recommend trying Inov8; the toebox is wide if I recall correctly, and not as ‘soft’ as the Altras.

YourSole performance thins have worked well for me in Altra (recommended originally to me by an Altra employee when they discontinued their stability wedges). Zero drop and good arch support. I don’t think much will help with reducing width however other than different footwear choice. Good luck.
