On the top is a Lake CX300 4-bolt Speedplay-specific shoe with the Speedplay Ultra-Light Action Walkable cleat, it fits nice and snug against the sole. On the bottom is a 3-bolt Rapha Climbers shoe using the standard 3-bolt shim and the light-action v.2 cleat.
I like the walkable cleats #lowasfuck stack height on a 4-bolt shoe. I had to drop my saddle height a full cm to compensate. On 3-bolt road shoes, I prefer the v.2 cleats with cafe covers. I think they fit the sole contours better.
The zero tension float is kinda weird at first, but it starts to feel normal quickly. By comparison, my Crank Brothers Eggbeaters on the War Monkey feel tight.
Those Lake CX300 shoes, otoh hurt my feet, and the carbon soles are slicker than goose shit. 😐
I mounted these up on some Speedplay 4-bolt Lake CX300 Carbon road shoes I picked up on clearance from The Pro’s Closet. Yeah, my curiosity currently has about a $300 price tag.
One final observation: the little cleat plugs Speedplay provides with the walkable cleats are a total joke.
