text: I have bought and worn 4 pair of these MW411 walking shoes.  I love the fit and feel.  For fitness, I used to run and wear running shoes but now, as I'm getting older (late 50s), I try to walk as much as I can every day.  My goal is to walk 5 miles a day and I'd say I come pretty close to that.  So my point is I walk a lot in these shoes.  My concern is I don't get full use out of these shoes due to poor bonding of the glue between the sole and shoe body.  Every single pair has failed in the exact same way.  The bottom separates from the body at/near the toe area then the separation gradually gets worse until the whole sole is separated down to the middle of my foot.  At that point, I throw them away and buy another pair.  I haven't tried gluing the sole back to the body as I've seen in other reviews.  The shoes fail at about the 4-5 month point for me.  Given my walking habits, that's perhaps 500 to 600 miles walked.  So I can't fault the shoe entirely.  That's a lot of miles!  But I do think New Balance should recognize this defect and use better glue.  I'd like to wear a hole in a pair or have the sole wear thin just once instead of watching what looks like a perfectly good pair of shoes come unglued!  My plan is to try another brand of walking shoe when the pair I have fails ... the soles are already starting to separate ... again!
