I've had a pair of Shimano MTB41's for as long as the o.p. has had the 22's. Maybe longer. They are still wearable but only barely. I looked them up but found that they too don't exist anymore. It would appear that the MTB50 is the closest modern equivalent to the 41's and there is probably an equivalent for the 22 as well. It's not that big a deal. I get the retro-grouch thing to a point. But only to a point. FWIW.
