I know this subject has been discussed but not sure my issue has been covered. I hav a pair of Danner Bighorns that I like quite well with the exeption of the soles. They have the Vibram aggressive tread & I keep getting hung up in higher grass which sometimes even results in a fall. My old body can't take many falls ! Any suggestions ? I do reqire a lightweight, non insulated, waterproof boot. Thank you, thank you very much.
