There are a few workouts that have short calf segments, like High Reps (with weights), Push/Pull (stick for balance and high step topper), Slow & Heavy Legs & Shoulders (with weights), Legs & Glutes (stick for balance and high step topper), Pyramid Lower Body (stick for balance and high step topper), and High Step Challenge (stick for balance and high step topper).
STS Disc 3 has a short calf segment during the 'meat' of the workout (with weights), then there is calf work in the bonus section of the workout too (on one leg with no weights).
Pure Strength Strong Legs & Abs (various methods are shown)
4 Day Split Lower Intensity Step has a calf segment that includes calves with no weights on the floor, calves with no weights on the high step topper, calves with weights on the floor).
Gym Style Legs has, imho, Cathe's toughest calves segment. No weights, just a stick for balance and a high step topper, but man-oh-man is it tough!
The leg discs from Meso 2 of STS 14, 17, 20, and 23 have a killer calf segment at the end of each one (using a weight, a high step topper, and a chair or barre for balance).
Turbo Barre has a calf work segment using the barre for balance.
That's all I can think of right now.
