> Depends on how you size them. If they are tight enough they edge really well, I’ve even been up things on the slate that obviously rely on edging to stand on anything. In contrast I’ve found the TX4s great on other terrain but I find they don’t edge well.
That could well be right - mine aren't that snug, bought for comfort rather than performance. Also, you are a much better climber than me so I suspect you could climb things in wellies that I couldn't climb in the best rock shoes, on a tight rope.
Like for like though, the TX4s soles seem to flare out a lot that must reduce edging performance compared to, say, Mescalitios.
