Customer Reviews

Comments: I bought these shoes based on info that they would accommodate after market insoles (most shoes will not and still leave room for your foot). I use lynco insoles for high archs and they work great in the 840. I started the shoe laces one hole up and laced the top to secure the heel. I have a narrow heel and wide fore foot. I have been using this shoe combination for 6 months and one half marathon. I have not tried the brook dyad which I read is a similar shoes to the 840 but I would be hard pressed to replace the 840's at this time
