Hi looking for a spray for my boots could anyone recommend one please

should have said textile boots

I like Nikwax for all my walking gear - they have a variety of products for cleaning and waterproofing a range of different fabrics.  They have a website you could have a look at.

Alternatively pop into any outdoor footwear store and they'll give you some recommendations too.  Another I've used is Brasher, which came free with a pair of their boots :)

Nikwax here too - excellent products and range :-)
