Following up the helpful advice I received here in Feb regarding running shoes for (very) wide feet:
1. The trail running shoes I bought from Decathlon in the autumn were very good but both split across the top after less than 100 miles. This might be because they were too tight, they certainly weren't comfortable. Anyway they fell apart but Decathlon would not refund
2. Following the advice here I ordered some wide Hoka and wide Brooks Cascadia in Feb. I kept only the Brooks which were marginally more comfortable. After 6 months of little running, again less than 100 miles I have given up on the Brooks. They were still a little too tight on the width so not 100% comfortable. But one of the inside seams rode up and caused blisters. To their credit, Runners World have taken them back and refunded.
3. I discovered that Hoka do extra wide fittings
only in one style as far as I can see so have ordered the Bondi 7. A few miles in, these seem promising so far but no idea if they'll last or survive the winter as they are not trail shoes (most of my running is off road)
Now that shops are open again I may venture in at some point and get some advice and try some on but options seem pretty limited. Sharing this in case anyone is in a similar predicament!
