Corrected entry: Kirk and McCoy start climbing the turbo shaft then Spock realises he can get them up the shaft faster with his rocket boots so he goes to get them. Then he comes down from above them which means he had to go up to whatever deck his boots were on to retrieve them. But if he was able to get that far up the ship without Sybok's soldiers spotting him, why not just have Kirk and McCoy go with him to the boot level instead of climbing the shaft from the very bottom?

Correction: Spock would have several advantages of going on his own. For one, it would be easier for one man to hide and avoid Sybok's soldiers then it would be for 3 men. And there would be less noise with just Spock going. Additionally, Spock's Vulcan hearing would make it easier for him to avoid the soldiers and he wouldn't have to communicate with the other two when someone is approaching or tell them where to go.
