Mtn Bike / Hike-A-Bike Shoes

Merrell Moab Ventilator, low-cut, wide (2E).

I got a pair at the REI used gear sale for $12.50 and put hundreds of MTB miles on them, including a bit of hike-a-biking when the need arose. They're fairly grippy on platforms with good pins, but nothing like a good pair of 5-10s. I don't ride with them since I switched to SPDs.

I have a separate pair that I used last year on a 77-mile hike. I cleaned them up and wear them around town, even to work on casual days.

Keen makes some of their walking/easy hiking shoes in "Pedal" versions, which are clip compatible (I think? I don't bike, so…). I have a pair of these that are fairly comfy http://www.sierratradingpost.com/keen-austin-pedal-lace-up-shoes-spd-compatible-for-men~p~5692w/?filterString=s~keen-pedal%2F&colorFamily=01

i will do everything in my five-ten guide tennies, bike, hike, and climb (Steel, for work).

I'll second the idea of Merrell Moab Ventilator, low-cut shoes.
Also, the Merrell Chameleon4 Stretch Hiking Shoe.

I have both, and have used them for hiking, mountain biking, and as approach shoes. They work pretty well for me for all 3 purposes. I'm sure you could find a better shoe for each use, but these have held up well and been comfortable for all 3 uses for me.

are you clipping in while biking or using flat pedals/toe straps?

I third the Moab Ventilator Low recommendation. Wear them all the time in the field and backpacking, and have been happy with them with platform pedals and some hike-a-bike (more on bad steep jeep trails, etc. than on singletrack where you might need to clip in).

Montrail would be my choice Max.

Edit: changed from Moontrail to Montrail.

I love my 510's but the Teva Links are pretty nice and comfy. They will all hike fairly well and will have excellent grip. My next shoes will be the 510 impact VXi's once they go on sale for the winter! 510's do wear out fast if you wear them around town though. FYI.

Ended up picking up the 5.10 Aescents, used, on eBay. I like them, and I'll try to keep their tread by not using them around town.

The grip on my pedals is nothing short of fantastic. I've taken them on a short hike and a short (unplanned) trail run, and they do a good job of deflecting pressure from rocks. It's very strange wearing all barefoot-style shoes for a long time and then putting these on.

Overall, though, I'm happy. The construction looks like hiking boots so they look durable.
