I go for zips just for ease of use. I've got two pairs - one only used for competition and the others, which are my old competition ones I wear at the yard 24/7. Very comfy and hard wearing.
the zips on mine always went as well, i stick to lace-up now.
although my Grasmeres are so comfy i might be wearing them all summer as well as all winter!
i've had zips for 3-4 months now and like them. had lace up boots before (not ariat) and liked them as well. If the boot is nice and snug with a zip then I would go for that option. if not, then would choose laces as you can obviously tighten them to fit.
I have the chaps as well, so not sure if that protects more than riding/wearing without as not much dirt can get in the zip.
I have the zip up Heritage ones, had them since last year and I use them both for riding and yard duties. Very comfortable, zips are fine although I only zip my halfway(chaps cover the rest)
Grasmeres are great aren't they Kerilli? I wore mine a lot during the summer as well and my feet stayed cool and comfy
I have both, and wouldnt know which to recommend more! I have two pairs with zips, one pair I have used every day for mucking out and riding for the past 8 years, and the right zip has only just started being faulty (goes down without me asking it to!) I have a lace up pair which, although I think they look smarter, they are perhaps less comfortable than the zip ups....and they are annoying to do up! Mum has a pair with laces on the front and a zip up the back - this seems a good happy medium!
I've got zip ones and had laces in the past. I prefer zips because they are much quicker and they use very strong zips so they do last. I suppose the lace ones are good if you have small ankles because they give you a bit more support because you can pull them up tighter.
