In reply to maxsmith:
Love my TX4s. Got them 18 months ago, just before a winter trip to New Zealand, so did, rain, snow, mud, ice, all no problems.
Super grippy, super comfy. Did try TX2s but these were laughably uncomfortable, like wearing chipboard.
Would happily by another pair - as it stands they're still in very good nick, given two winters and a summer of wear.
Cheers
