Are my hiking boots suitable for climbing Kilimanjaro?

I have the Storm Womens IsoGrip Waterproof Hiking Boots from Mountain Warehouse. I am hiking Kilimanjaro via the Machame route in August. Are these ok? I've worn them a couple times before for short treks and hikes and they seem ok but this is much more extreme than an average hike in the UK.

Please also do let me know if you have any gear you would recommend for Kili.
