The best approach shoes I've ever had.

I've owned two pairs of the Guide Tennies and three pairs of the Mountain Masters. The Guide Tennies are great for scrambling and moderate climbs. These shoes are extremely comfortable, but every pair I've owned this delaminated at the toe.

I like the way these shoes fit and the rubber is really good for approach shoes. I do think that the workmanship could be alot better. After only a couple of months of light use, the rubber at the end of the toes, on both shoes, started to de-laminate. I was wearing them while hiking/climbing in Zion and the front 1/3 of the sole on the right shoe came completely unattached from the rand. I had to tape the shoe up for the final 2 miles of the trail back to the trailhead. If you plan on doing anything other than short approaches, I would suggest looking at shoe that is built a little beefier.

Get a pair. These are the best and most comfortable shoes I've owned. When the tread is new they grip like no ones buis-ness!! I've now had my pair for going on 2-1/2 years. They are now pretty much slick on the bottoms but fit my foot like a glove.

I've climbed relative easy climbs up to 5.7 out @ red rock. I love the comfort I have while hauling my gear out to a climb.

I wear the hell out of them also around town as they are comfortable and sport a style different from the norm.

I've had several people comment on the style and want to know what and where to get them, who don't have a clue about what rock climbing is all about.

With this said, I've now owned three pairs of these shoes. The second pair delaminated at the toes like previously mentioned by others. I spoke with 5.10 and they without hesitation replaced them.
While I love the stickiness of the rubber soles, they are known to leave marks on flooring and wear smooth within a year or so for me. I also see that the padding in the heel area wears out fairly quickly. And while I really like these shoes I am now beginning to look to replace them with a more durable shoe.

Coming back from an injury my orthopod suggested that I get a pair of shoes that don't compress my feet so much. Normal climbing shoes compress the bones and structure of your feet in order to give you more control. But that compression leave you more vulnerable to injury because there is less give in the foot if you fall on it. I took these shoes to the gym yesterday and was amazed at what I could climb with them. They edged really well even on small holds and they smeared fine. At the level I climb (10ish) I may not need go back to normal shoes. They're really comfortable. I don't wear them around town because of the sticky rubber wearing out, but I'm sure they would be great for approach.
