Otherwise pop down sports direct and get a decent pair of waterproof gortex / event walking shoes / boots.
I have those exact same boots, while great for walking, I would hate to use them on the bike.
The sole is far too stiff for me and would give me poor feedback. The rubber compound is also quite hard and the tread pattern has many gaps so I’m not sure would grip the pedal well as many pins wouldn’t be in contact with any rubber.
Probably most importantly they are far too stiff in the ankle and I don’t think I would be able to get my heels down properly or fully move around on the bike.
