Sorry to hear that happened to you
@Josephine Bloggs. I also fall over easily and agreed with
@Mustard - Merrell are excellent. Grippy soles, comfortable and last for years.
If you are in a budget, Decathlon do their own brand copies of Merrell and if you are near a Decathlon store you can try them all on. (And Decathlon also stock Merrell).
If you need to wear something more ‘fashion’ (eg for commuting to work) you can get YakTrax. They fit onto most shoes and boots, you can take them on/off as you need it. YakTrax is the original brand but if you look on Amazon there are cheaper versions.
Finally... not as grippy as Merrell but it might be worth a look at Dr Marten. They have expanded in recent years and now have styles that are more streamlined and less ‘street’ than the originals, but still a lot more sturdy than your average high street boot.
