It seems from your description that your flooring is doing a reasonable job of removing the blu-tack so it must be possible to remove :) I would mechanically scrape as much as I could using a knife, cocktail stick/kebab skewer, screwdriver or similar and then for the final remaining bits I would repeatedly and firmly dab them with a lump of blu tack (...

My experience is that BluTac seems to get softer and happier to stick to more BluTac if mechanically worked and warmed up.

Do you have access to an engine-powered pressure washer? Put on your goggles, affix the shoe to a strong post and blast the Blu-tack out of the cracks and crevices with the fan-shaped high pressure stream. I've done this on automotive floor mats to remove tar and chewing gum with no damage.
