Durable rubber knee boots?

Does anyone have recommendations for a brand/style of rubber knee boot which is reasonably durable?

I've had (in no particular order):
- Honeywell Servus
- Red Ball
- Itasca
- and now, Muck
rubber knee boots.  The jury is still out on the last one, because I just started wearing them today.  My wife bought them for me this summer at our local grocery store, on sale.  Yep, that's the kind of grocery store we have - boots on sale.  Frankly, I don't have extremely high hopes for the Muck boots either, since the guy I share an office with has had two pairs replaced under warranty because they leaked due to the over mold separating from the upper.

The typical mode of failure for me is that the rubber cracks.  I then ShoeGoo the crack (multiple thin layers), after which the rubber cracks somewhere else, and so on.  If it's reasonably dry, I eventually give up on repeated repairs and just wear them.  But, if it's reasonably dry, I don't probably need knee boots, either.

I don't think anything I do should be particularly hard on them.  I don't snowshoe in them, I don't use them to pour concrete (mostly).  I don't clamber over rock piles of broken basalt in them (trust me, it's a thing).  I wear them berry picking, and with wool socks in warmish winter temps (typically, above 20F).  A bit of winter shoveling, again in warmer winter temps.  I have Baffin pack boots for cold weather.  I don't wear them on long walks.  I may use them when I put our little kayak dock in the lake, unless they've dropped the stop logs at the dam to raise the water level, in which case I'll wear my waders.  I don't log in them.  In short, I would think they should have a pretty easy life, but within a year or so, I am usually seeing the first signs of cracking.

Does anyone have suggestions for durable rubber knee boots?

My Mucks are about 4 years old now.


Update:   I found an old post of mine.  I bought my Mucks in Jan 21.   So my 4 year estimate is pretty accurate.   What attracted me to them was the comfort level.

John -

Well, here's to hoping, then.  This is the first pair of Muck boots I've had.  The style I selected from the limited selection (at the grocery store, mind you) don't have the fancy overmold, like my office mate's did/do.  Mine are just plain black.  His were Realtree camo or something - way fancy looking - with the overmolded toe cap.

If the Muck boots don't last, I may up the ante, and try Honeywell Ranger boots.  They are not inexpensive (but, then, neither were the Muck boots, even on sale).  I probably don't need hard toes, with electrical insulation specs , big pull loops, logger's caulks, metatarsal guards and so forth, which seem to be part and parcel of the Ranger line, in some combination or other, depending on model.  But, I may just need to step up to professional grade boots, even if I'm a rank amateur.

Thanks for the vote of confidence in the Mucks.  4 years seems more that reasonable, to me.  Barely one year?  No, I expect a bit more than that, given that I don't ride 'em hard and put 'em away wet, so to speak.
