Sidi On Road

I tried it on my dad's bike shoes SIDI (road) and they have the strap on top of the clicks into place with a slope of leverage, but now I get so how can I cancel the top plastic strap clicking

It Sholder be a little ratchet lever that lifts up or pushing down. It will come out of the loop.

If I had a picture, I could probably tell you, but I do not know what you are working with.

Thus, Plan B - ask Dad. He should know! (But this plan could involve some degree of embarrassment!)

Of course, you asked what time ago, and you wore these shoes for an hour, and they probably really suck at walking (MTB shoes are generally better) and you've probably tried really hard to get off and I bet they're gone now.

But if not, post a photo of them somewhere and give us a link or find the make and model and call the manufacturer and ask them for help. They could also have an online manual.

The shoes are shoes I use ATV (but I use on my road bike - SPD compatible) by Cannondale and are equipped with Velcro straps. Very easy to get.
