I've got the old Exustar (SS502, 2-strap, protected toe), and old Shimano (SD66, 2 strap, open toe).
The Exustar is the 3rd pair of similar I've had - on one pair the cleat slots broke fairly early on, the other had a lot of wear and tear, with the strappy bits on top breaking and being stitched back together, before the plastic insole split at the walking flex point. The patterned footbed is also quite uncomfortable at first if you walk much whilst it's new, but is OK after a while.
I didn't like the enclosed nature of the SS503 (3 straps, mesh between the straps on top), so I got the SD66 as a second pair. They have been fine so far.
Both are OK up to 200k, not tried them further.
I initially got them for touring, but I've only been using shoes when it's too cold (below 5°C) for the last 4 or 5 years.
I'm 46 in regular shoes, I got the 45-46 option
Buying again, I'd currently get the SD5.
The old Exustar is still available from Bike Nashbar as the Ragster II.
