Yup, blisters here they come. I used to break Summer shoes in days, flip them off my feet just walking (I have high insteps) I've even melted the soles. Happily, I have been buying better shoes for the past few years, no more high-street apart from Doc Martens. At least with
Gucci, Hermes and Ferragamo shoes I've had no problems (yet). I like clogs in the Summer, I need to get my Gucci clogs (2016) re-soled and then at least I'll have Oxfords, loafers and clogs.
Best time to remodel is often Spring/Summer, furriers have more time, towards the end of August they have waiting lists 'suddenly' remembering their fur needs work. On the plus side, if you have a bit more time to consider, you'll be all the more confident when the time comes to get the work done, remodelling is never cheap.
