I have the Spadas. The sizing is weird.
Mine are large. They’re tight round the ankles, but they fit fine over SealSkinz (or possibly Aldi’s own equivalent) and create a nice seal.
They’re also snug around the calves and thighs, but seem to have just enough give. I managed a lap of Cut Gate in relative comfort.
Like others have said, I’d have been tempted to size up for the leg space, but the waist is already a bit big. With the ratchet done full up it’s just about okay.
I wonder if they’re not really designed for us mountain bikers with mighty legs. I think Spada are a motorcycle clothing company originally.
