My very nice Sidi road shoes must have loosened up a bit since new and I’ve noticed I’m getting a little heel lift on my last couple of rides despite best efforts with adjusting the Velcro and ratchet straps. Can you get heel grips that you fit inside the shoe to help with this? My friend google didn’t throw up anything obvious when I’ve just searched - almost too much choice! Alternatively would replacement inner soles be better? Any recommendati9ns or advice?
