In reply to Dave the Rave:
>I’’m looking for a shoe with good cushioning, good grip on mud and with quite a wide toe box. I used to run in Walsh PB’s. Should I just get another pair?
I have some PB's. They have no cushioning, excellent grip and are narrow. You can probably get them for around £80.
I'd have a look at the trails you're running on. Well made tracks and fire roads, then go for trail shoes. Bogs, mountains, and steep stuff, then fell shoes like Walshes.
Three miles isnt a lot, so you can probably get away with most shoe types. I'd have a look on sportsshoes.com and see what they have in the sale. (You could get a pair of asics and and a pair of new balance, trail shoes, and still have enough change from your £80 to get a pint.) Pete Bland are a good independant. Inov8 cover every terrain and have a range of widths, but they seem to have gone up in price. Similar story with Salomon speedcross, though they sometimes have other discontinued lines that are cheaper.
