My first clipless pedals in the early 1990's were Look road pedals with their three-bolt cleats. These convinced me of two things: 1) I never wanted to go back to quill pedals with toe clips and straps and 2) single-sided pedals with slippery, exposed cleats were not the thing if you rode in any kind of traffic or hilly city/suburban conditions with stop signs, traffic lights, etc. They were fine for racers who clipped in once at the beginning and out at the end of a race or training ride but not in between and never walked in them. That was not my type of riding and as soon as walkable cleats and two-sided pedals were available I switched immediately.
My first recessed cleat, double-sided pedals were Speedplay Magnums that soon morphed into Frogs. I have ridden over 100,000 miles on three pair of Frogs and really liked them. Yes, they have a huge amount of float but that was never a problem. I use them mostly with Shimano's SH-T09X, and SH-RT8X Touring shoes (two-bolt SPD recessed cleat pocket, flat lugless soles) and the stiffness was adequate for long rides with no foot pain. That said, they were expensive, required routine relubrication, repair parts for the pedals and cleats were difficult to find, cleat durability was mediocre and, as above, Speedplay's support was unpredictable. Also, despite their claim of being MTB pedals, their mud and dirt tolerance was poor and the cleats clogged easily.
Yes, Frogs are listed on Speedplay's website but "Not available at this time.....", as are all of their MTB/Touring type pedals. The only ones currently available are the various "lollypop" road pedals. Speedplay has been known for vaporware in the past and that seems to still be the case.
When my last pair of Frogs wore out I switched to Shimano SPD XT-level MTB pedals with the same shoes and have used then on all of my bikes since. The more modest float is perfectly adequate and the durability has been great. Also, the pedals and cleats are available everywhere and repairs and maintenance on the pedals themselves have been unneeded.
