A) I want some protective footwear - to stop toes getting hurt by angle

B) My feet are very unusually shaped and I need HH+ width and have a
very high instep.

I get my shoes from Cosyfeet - who do not do protective shoes.

Not looking for any special style - maybe a trainer-style would be most
comfortable? But I don't seem to be able to find any.

Any suggestions for suppliers?

(Note: Intentionally applying angle grinder to feet to reduce width is
*NOT* an option. :-) )

I have a higher than normal arch and am currently waering Sterling brand
Safety Trainers (Screwfix 37220). My shoe size is 6.5 to 7 and the size
7 of these seems to have plenty of room inside. They are also available
from TLC. You might be able to go into one of these places and try them on.
